Which one of the following Keyword-driven input tables provides the BEST test coverage of this enhancement?

An enhancement to a Social Media application allows for the creation of new Groups. Any number of existing application members can be added to a Group. An attempt to add a non-existent member of the application to a Group will result in an error, as will an attempt to add the same member twice.

Members can be removed from an existing Group. An existing Group can be deleted but only if there are no current members attached to it.

Answer: D

Explanation:

Table 2 provides the best test coverage because it includes tests for adding a non-existent member (Member4), which should result in an error, and it also tests for removing a member and then deleting the group, which is the correct sequence of actions according to the requirements. The other tables either do not test all the required scenarios or have actions in the wrong order (e.g., attempting to delete the group before removing all members).
