Answer:

The relationship between "book and index of the book" is that of a “composition” as per "Object Oriented Programming (OOPS)" concepts. In this relation, one object is contained by other object and the contained object cannot exist alone. Index of the book cannot exist without the book; hence they share composition relationship between them. "Restricted form of aggregation" is "composition".
