To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) A Servlet is a Server-side entity that will rest only on the Server - This option is correct. A Java Servlet is a server-side technology that runs on the server and handles client requests. It is not meant to be run on the client-side.
Option B) The life-cycle management of Servlets is done by the programmer - This option is incorrect. The life-cycle management of Servlets is handled by the Servlet Container, not the programmer. The Servlet Container is responsible for creating, initializing, invoking, and destroying Servlet instances.
Option C) Java Servlet Technology provides support for handling XML requests through a special Servlet called XmlServlet - This option is incorrect. Java Servlet Technology does not provide a special Servlet called XmlServlet for handling XML requests. Servlets can handle any type of request, including XML, but there is no special Servlet specifically for XML requests.
Option D) A Servlet instance is created by the client during the first request to the Servlet Container - This option is incorrect. The Servlet instance is not created by the client. It is created by the Servlet Container when the container is started or when the first request for the Servlet is received. The client only sends the request to the Servlet Container, and the container handles the creation and management of Servlet instances.
The correct answer is Option A. A Servlet is a Server-side entity that will rest only on the Server. This option is correct because Servlets are server-side technologies that are executed and managed on the server, not on the client-side.
