The correct answer is B: 2.

Explanation: Types of Polymorphism

In C++, polymorphism is broadly classified into two main types based on when the binding (the association between a function call and the actual function definition) occurs.

1. Compile-time Polymorphism (Static Binding/Early Binding):

   This type of polymorphism is resolved during the compilation process. The compiler knows which function to execute based on the function signature (name, parameter types, number of parameters).

   • Examples: Function overloading and operator overloading.

   • Mathematical representation:

     $$Resolved\_At=Compile\_Time$$

2. Runtime Polymorphism (Dynamic Binding/Late Binding):

   This type of polymorphism is resolved during the execution (runtime) of the program. It typically involves the use of inheritance and virtual functions. The program decides which function to execute based on the actual object type at runtime.

   • Examples: Function overriding (using virtual functions).

   • Mathematical representation:

     $$Resolved\_At=Run\_Time$$

Summary Table

By understanding these two categories, you can effectively manage how methods and operations behave in your C++ applications.
