Answer 1

Answer:

QUESSTION 1: B

QUESTION  2: C

QUESTION 3:  D

Explanation:

In question 1, since A3 extends A2, it implies A3 is the subclass of A2 and A2 is its super class, same applies to the relationship between A1 and A2, the extends keyword is used to indicate inheritance in the child class (subclass)

In question 2, the class A2 has two declared instance variables (a,b) It has also inherited the public variables of its superclass (A1) so it has the x,z (Inherited variables) and a,b (its own variable)

The same explanation in question 2 applies to question three. The Class A3 has access to all the public fields of A1 and A2 as well as its own declared field x,z,a (Inherited public fields) q Its own field.
