d. Inheritance.

Explanation:

The two classes are book and novel.

Since the class novel is derived from the class book, then the relationship between them (these objects) is inheritance. Inheritance is "is-a" relationship.

In this case, a novel "is a" book.

Inheritance is one of the principles of object oriented programming (OOP) in which a class, called the sub class or child class, derives, extends or inherits features of another class, called the super class or parent class or base class. In other words, in inheritance, a sub class is derived from another class in such a way that these classes have an "is-a" relationship.

In this case, the novel is the sub or child class while the book is the super, base or parent class.
