Well it can be either C or D. C is a reasonable choice because when doing the exercise you tend to comprehend what you're learning as you're going. D is also reasonable because it does show how one word ties in with many others. I hope with this you're able to decide. Have a nice day! :)
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 <em>which is crucial to enhance reading comprehension among them</em>. Augmenting vocabulary help the students to understand new words and inculcate new information in them. <em>Thus, it eventually improves the reading comprehension of the student. </em>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.
