ITPEC IP April 2026 — Question 28 of 100
Publishing Company → Author → Book — both relationships are one-to-many in the stated direction.
One publishing company contracts with many authors, while each author has only one company, so the arrow points from Publishing Company to Author. One author writes many books, while each book has one author, so the next arrow points from Author to Book.
Answer (a)
Why not others: (b) reverses the author-book relationship; (c) reverses the company-author relationship; (d) reverses both.
Key rule: For each pair, identify the entity on the “one” side and point toward the entity on the “many” side before combining the relationships.
