Which line is written at the top of the script to write a Perl script using CGI.pm?

Solution (By Examveda Team)

This question is about writing web applications using Perl and a library called CGI.pm. CGI.pm is a powerful library that helps you create web pages dynamically.

To use CGI.pm in your Perl script, you need to tell the Perl interpreter to "load" or "use" this library. This is done with a special line at the beginning of your script.

Out of the options given, only Option C: use CGI is the correct way to include the CGI.pm library in your Perl script.

The line use CGI tells Perl to load the CGI.pm library, giving you access to all its powerful features.

Let's break down why the other options are incorrect:

* Option A: use this CGI: This is not a valid way to include a library in Perl. The word "this" isn't used in library inclusion. * Option B: put CGI: This is also incorrect. The keyword "put" is not used for including libraries. * Option D: include CGI: While "include" can be used in some programming languages for libraries, it's not the standard way to include libraries in Perl. The "use" keyword is preferred.
