Answer

(iii) HTTP

Explanation

AJAX allows a browser to communicate asynchronously with a server. The XMLHttpRequest API commonly sends requests using HTTP (or HTTPS).

  • WWW is the overall Web system, not the protocol used for the request.
  • SMTP is used for email transfer.
  • HTTP is the standard request/response protocol used by AJAX communication.
