Answer D:
As per the classes definitions, the Tiger is a Cat, but the Cat is not a Tiger. So we cannot add Cat classes to Tiger array list. Vice versa works though.
Correct answer should be D.
D fails and the compiler will ask you to cast new Cat() into Tiger.
Correct answer is D, you cannot add Cats to Tiger List
