To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) More interactive and faster - This option is correct. AJAX (Asynchronous JavaScript and XML) allows web pages to update content dynamically without reloading the entire page. This makes the web page more interactive and faster since only the necessary data is fetched from the server and rendered on the page, rather than reloading the entire page.

Option B) Easy to connect web page with server - This option is correct. AJAX enables communication between the web page and the server in the background, without interrupting or reloading the entire page. This makes it easier to connect the web page with the server and retrieve or send data without disrupting the user's experience.

Option C) More dynamic - This option is correct. AJAX allows for dynamic content updates on a web page without the need for a full page reload. This means that content can be updated or changed based on user actions or server responses, making the web page more dynamic.

Option D) All the above - This option is correct. AJAX provides all of the mentioned benefits. It makes web pages more interactive and faster, allows for easy connection with the server, and makes web pages more dynamic by enabling content updates without reloading the entire page.

Therefore, the correct answer is D) All the above.
