composer

The correct answer is "composer."

To determine the correct answer, it is important to understand the relationships between the given words. In this analogy, the word "author" relates to "novel" because an author is the person who writes a novel. Similarly, we need to find a word that relates to "composition" in a similar way.

A "composition" refers to a piece of music that has been written. So, to find the word that completes the analogy, we need to identify the person who writes music. This person is called a "composer." Therefore, the correct answer is "composer," because just as an author writes a novel, a composer writes a music composition.
