Quizplus · Accepted Answer

A class that implements an interface but does not declare all of the interface's methods must be declared as abstract with the abstract keyword or as mustinherit with the mustinherit keyword. However, it cannot be declared as final as final means it cannot be inherited. It also cannot be declared as an interface as it is already implementing an interface. Therefore, the best choice is C, mustinherit.
