Answer:

d. None of the above.

Explanation:

a. Method originalMethod cannot be overridden in class C—once it has been implemented in concrete class B, it is implicitly final.

c. If method originalMethod is not overridden in class C but is called by an object of class C, an error occurs.

d. None of the above.
