Can a pure virtual function have a definition in C++?

Yes, always
No, never
Yes, but only in derived classes
Yes, in the base class

The correct answer is: Yes, in the base class

A This is incorrect because pure virtual functions cannot have any definition in the base class. B: This is also incorrect because a pure virtual function can have a declaration with no definition in the base class. C: While this may seem correct, it is not the most accurate answer. A pure virtual function can have a definition in a derived class, but it must also be overridden in any further derived classes. D: This is the correct answer. A pure virtual function can have a definition in the base class, as long as it is not used to create objects of that class and is overridden in any further derived classes.
