    Answer : Option C

    Explanation :

    (3), (6). Both are legal class declarations.

    (1) is wrong because a class cannot be abstract and final—there would be no way to use such a class. (2) is wrong because interfaces and classes cannot be marked as static. (4) and (5) are wrong because classes and interfaces cannot be marked as protected.
