OK

There are two solutions, as far as I know.

both that just need using vanilla javascript

1 selectedOptions

<div class="select-box clearfix">
  <label for="area">Area</label>
  <select id="area">
    <option value="101">A1</option>
    <option value="102">B2</option>
    <option value="103">C3</option>
  </select>
</div>

const log = console.log;
const areaSelect = document.querySelector(`[id="area"]`);

areaSelect.addEventListener(`change`, (e) => {
  // log(`e.target`, e.target);
  const select = e.target;
  const value = select.value;
  const desc = select.selectedOptions[0].text;
  log(`option desc`, desc);
});

2 options

<div class="select-box clearfix">
  <label for="area">Area</label>
  <select id="area">
    <option value="101">A1</option>
    <option value="102">B2</option>
    <option value="103">C3</option>
  </select>
</div>

const log = console.log;
const areaSelect = document.querySelector(`[id="area"]`);

areaSelect.addEventListener(`change`, (e) => {
  // log(`e.target`, e.target);
  const select = e.target;
  const value = select.value;
  const desc = select.options[select.selectedIndex].text;
  log(`option desc`, desc);
});
