Answer is Wrong!
The correct answer is D. all of the mentioned.
AJAX stands for Asynchronous JavaScript and XML. It is a technique for creating interactive web applications that are more responsive than traditional web pages. AJAX allows web pages to update content without reloading the entire page.
The ScriptManager control is a server control that enables you to add script files to your web pages. The ScriptManagerProxy control is a server control that enables you to use AJAX in web pages that are not hosted on a server. The UpdateProgress control is a server control that enables you to display a progress bar while a page is loading or updating.
All of these controls are used to implement AJAX in ASP.NET web pages.
