Explanation:

A word map is a visual developer that advocates vocabulary development and assists the students to learn concepts and terms in several ways. This involves the students in establishing a definition, synonym, antonym of a given word or vocabulary that aids them to learn new concepts which is crucial to enhance reading comprehension among them. Augmenting vocabulary help the students to understand new words and inculcate new information in them. Thus, it eventually improves the reading comprehension of the student. The other options are incorrect as the aim of a graphic word organizer is to teach new concepts and not mere mugging up the words, antonyms or definitions.
