AI Explanation

To answer this question, you need to understand the role of JSP (JavaServer Pages) and its transformation process.

JSP is a technology used to create dynamic web pages. It allows developers to embed Java code within HTML pages, which is then executed on the server side. JSP pages are transformed into Java servlets during the compilation process.

Option A) Java applet - This option is incorrect because JSP pages are not transformed into Java applets. Java applets are client-side programs that run within a web browser and are embedded within HTML pages.

Option B) Java servlet - This option is correct. JSP pages are transformed into Java servlets. Servlets are server-side programs that run on a web server and generate dynamic content to be sent back to the client.

Option C) Either 1 or 2 above - This option is incorrect because JSP pages are specifically transformed into Java servlets and not Java applets.

Option D) Neither 1 nor 2 above - This option is incorrect. JSP pages are transformed into Java servlets, so option D is not the correct answer.

The correct answer is B) Java servlet. This option is correct because JSP pages are transformed into Java servlets during the compilation process.
