A version of foo1() called

The Correct option is (c)

A() called

B() called

B version of foo1() called

Reason:

statement B b2 = new B(); creates new instance of class B.

When an object is created, first the constructor is invoked.

The 1st statement of B's constructor invokes A's Constructor.

Hence

A() called

After the statement in B's constructor is printed.

B() called is printed.

Later B's foo1() method is invoked.
