In a many-to-many relationship, each entity on one side of the relationship can be associated with multiple entities on the other side. For choice A, each single-authored book is associated with exactly one author, and each author can write multiple books, but the relationship specified is between authors and single-authored books, implying a one-to-many relationship, not many-to-many. Choices B, C, and D describe scenarios where entities on both sides of the relationships can have multiple associations with entities on the other side, fitting the definition of many-to-many relationships.
