In C++, polymorphism requires Inheritance, Virtual functions and references.

Here's why:

1. Inheritance: This is the mechanism of basing an object or class upon another object or class, retaining similar implementation. Inheritance allows programmers to create classes that are built upon existing classes. It enables a class to inherit the properties and methods of another class. This is important for polymorphism as it allows a subclass to be treated as its superclass.

2. Virtual Functions: These are used to achieve runtime polymorphism. They are declared using the virtual keyword, and can be redefined in the derived class. It is what makes the compiler to perform dynamic linkage or late binding on the function.

3. References: References are used to achieve polymorphism when we want to call a function that has been overridden in a derived class using a reference of the base class type to an object of the derived class.

So, all three - Inheritance, Virtual functions and references are required to achieve polymorphism in C++.
