To answer this question, you need to understand the concept of AJAX (Asynchronous JavaScript and XML). AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes.
Option A) True - This option is correct. AJAX applications are browser- and platform-independent. This means that AJAX can be used on different web browsers (such as Chrome, Firefox, Safari, etc.) and different platforms (such as Windows, Mac, Linux, etc.) without any compatibility issues. AJAX is based on open web standards like JavaScript and XML, which are supported by most modern browsers.
Option B) False - This option is incorrect. AJAX applications are not tied to a specific browser or platform. They can work on multiple browsers and platforms.
The correct answer is A) True. This option is correct because AJAX applications are indeed browser- and platform-independent.
