For a particular function somefunc of a base class called SomeBaseClass, where somefunc has one integer parameter called x and returns a float, we wish to enforce dynamic binding on the name of the object for which this function is called (for this class and all derived classes that override the function. The function prototype of somefunc in SomeBaseClass might look like this:

A. dynamic float somefunc( int x );
B. dynamic_bind float somefunc( int x );
C. virtual float somefunc( int x );
D. protected float somefunc( int x );
