d. none
Answer  Explanation 

ANSWER: Compile time polymorphism

Explanation:
The property of function overloading is also known as Compile time polymorphism. Here in this code we see how a function is overloaded using different datatype, different number of arguments and default argument. Function overloading is a concept which allows the use of same function name to different functions for performing same or different task in the same class.
