Correct Option: A

AI Explanation

To defeat browser cache, you can use the "nocache=true" option.

Explanation:

Option A) nocache=true - This option is correct because it instructs the browser to not cache the requested resource. By adding this parameter to the URL or request, the browser will always fetch the latest version of the resource from the server.

Option B) cache=false - This option is incorrect because there is no standard cache parameter called "cache" that can be set to false. This option does not exist.

Option C) nocacherequired=false - This option is incorrect because there is no standard cache parameter called "nocacherequired" that can be set to false. This option does not exist.

Option D) None of the above - This option is incorrect because option A, "nocache=true", is the correct option to defeat browser cache.
