Solution

The correct answer is a. Both the derived class constructor and the base class constructor get executed.

Here's the step by step explanation:

  1. When an object of the derived class is created, the derived class constructor is called.
  2. But before the derived class constructor executes, the base class constructor is called.
  3. The base class constructor executes first and initializes the base class data members.
  4. After the base class constructor finishes execution, the control returns to the derived class constructor.
  5. The derived class constructor then executes and initializes the derived class data members.
  6. Finally, the derived class object is fully created.

So, both the derived class constructor and the base class constructor get executed when a derived class constructor is called.
