  You can achieve this by using the onchange event in jQuery. First, you need to fetch the latest cryptocurrency price data using an API. Then, you can populate the select dropdown options with the cryptocurrency names. When the user selects a cryptocurrency, you can use jQuery to get the selected value and fetch the corresponding price from the API. Finally, you can display the price in a separate section of the page. Make sure to handle any errors that may occur during the API request. Good luck with your implementation!
