Question

(a) Class A

(b) Class B

(c) Class C

(d) All together

I had been asked this question in an international level competition.

I'd like to ask this question from Multiple Inheritance in chapter Inheritance & its Types of Object Oriented Programming

Answer 1

The correct option is (b) Class B

Best explanation: The constructors of parent class will be called first. In that, the constructor of the classes will be called in the same sequence as that mentioned in class definition inheritance. Since class B is mentioned first for inheritance, its constructor will be called first.
