The keyword MustOverride is used in a MustInherit class to define methods that must be implemented in a derived class for that derived class to be concrete. Option A (Overridable) allows a method to be overridden in a derived class but is not necessary for the derived class to be concrete. Option B (Abstract) also requires derived classes to implement the method, but it can be used in non-MustInherit classes as well. Option D (MustImplement) is not a valid keyword in VB.Net.
