Question
class A, B and C are in multilevel inheritance hierarchy repectively .

Solution
The correct answer is: Constructor of A executes first, followed by the constructor of B and C.
In a multilevel inheritance hierarchy, the constructor of the base class (A) is called first, followed by the constructor of the next derived class (B), and finally the constructor of the most derived class (C). This is because the derived class inherits the properties of the base class, so the base class must be constructed first.
