Display drop box item selected price from API

What do I want to achieve ??

I want to display the price of each item selected from the dropdown box using API. I tried to use click event but it's too hard for me right now as I am a beginner . Can someone help me displaying the price of the selected item from the drop-down box in a span in the bottom left corner of the form when we select one option?

const apiData =[
  {
      "id":"1",
      "question" :"Love",
      "price":"90"
  },
  {
      "id":2,
      "question":"Carrer",
      "price":"80"
  },
  {
      "id":"3",
      "question":"Shadi",
      "price":"100"
  },
  {
      "id":"4",
      "question":"Future",
      "price":"200"
  },
  {
      "id":"5",
      "question":"Office",
      "price":"300"
  },
  {
      "id":"6",
      "question":"After-Life",
      "price":"400"
  }
]


//Js Code for diplaying items in drop box (working prefectly fine)
async function loadUsers() {
  //const response = await fetch("../reference_json/questions_API.js");
  //return response.json();
  return apiData
}

document.addEventListener("DOMContentLoaded", async () => {
  try {
    const users = await loadUsers();
    const divContainer = document.getElementById('question');
    users.forEach(user => {
      const paragraphElem = document.createElement('option');
      paragraphElem.innerText = `${user.question}`;
      divContainer.appendChild(paragraphElem);
    });
  } catch (e) {
    console.log('ERROR');
    console.log(e);
  }
});

<form class ="choose-form">
        
        
  <div class="mb-3">
    <select  class="form-select" id ="question">
      <option>Select a category : Love,carrer,more ...</option> 
    </select>
  </div>

  <nav class="navbar navbar-expand-lg navbar-light">   
    <span> ₹99(including GST)</span>
    <span>Ideas what to ask</span>
    <div class="profile-icon" style="justify-content-end">
      <button type="submit" class="btn btn-warning">Ask a Question </button>
    </div>
  </nav>
</form>

since you are calling data from ajax you have to save all values needed while loading it from server then bind an onchange event on select element then print value from selected option to your span

here is the corrected code below

const apiData =[
{
    "id":"1",
    "question" :"Love",
    "price":"90"
},
{
    "id":2,
    "question":"Carrer",
    "price":"80"
},
{
    "id":"3",
    "question":"Shadi",
    "price":"100"
},
{
    "id":"4",
    "question":"Future",
    "price":"200"
},
{
    "id":"5",
    "question":"Office",
    "price":"300"
},
{
    "id":"6",
    "question":"After-Life",
    "price":"400"
}
]


//Js Code for diplaying items in drop box (working prefectly fine)
async function loadUsers() {
//const response = await fetch("../reference_json/questions_API.js");
//return response.json();
return apiData
}

document.addEventListener("DOMContentLoaded", async () => {
try {
  const users = await loadUsers();
  const divContainer = document.getElementById('question');
  users.forEach(user => {
    const paragraphElem = document.createElement('option');
    paragraphElem.innerText = `${user.question}`;
    // edited line saving matching data to option
    paragraphElem.data = user
    divContainer.appendChild(paragraphElem);
  });
} catch (e) {
  console.log('ERROR');
  console.log(e);
}
});

// edited line
var select = document.querySelector("#question"),
  priceEl = document.querySelector(".priceShow")
select.onchange = function(){
    var selected = select[select.selectedIndex],
        value = typeof selected.data != "undefined" ? selected.data.price:null
    if(value){priceEl.innerText = `₹${value}(including GST)`}
}

<form class ="choose-form">
    <div class="mb-3">
      <select  class="form-select" id ="question">
        <option>Select a category : Love,carrer,more ...</option> 
      </select>
    </div>

    <nav class="navbar navbar-expand-lg navbar-light">   
    <!-- edited line -->
      <span class="priceShow"> ₹99(including GST)</span>
      <span>Ideas what to ask</span>
      <div class="profile-icon" style="justify-content-end">
        <button type="submit" class="btn btn-warning">Ask a Question </button>
      </div>
    </nav>
 </form>
