What keyword in C++ enables polymorphism?

static
virtual
const
extern

The correct answer is: virtual

In C++, the virtual keyword enables polymorphism by allowing a class to provide different implementations of functions within derived classes. The other options do not directly enable polymorphism. Static is used to define static variables or functions, const is used to specify constant variables, and extern is used to declare global variables. Although const and extern can also be used in C++ polymorphism, they are not the enabling keyword. Therefore, option B is the correct answer.
