<span>The correct answer is C. The most common linking verbs are various forms of the verb "to be." These are: am, is, are, was, were, be, being, and been. Linking verbs show a relationship between the subject and the subject complement -- which is really just a fancy way of saying that linking verbs connect (or link) a subject to more information about the subject. Consider this example: Julie is my sister. Here, the linking verb "is" connects the subject (Julie) to more information about the subject (the fact that she is my sister). Using a form of the verb "to be" is the easiest way to link this information; therefore, the correct answer is C.</span>
