Which one of the following statements is true for the base forms of verbs?

AAdd "to" to the base form to create an adjective.
BWhen the subject of a sentence is singular, add "–s" to the base form.
CAdd "–ed" to irregular base forms to form the past participle.

Verified Answer :

The correct answer for the given question above would be option B. The statement that is true for the base forms of verbs is that, when the subject of a sentence is singular, add "-s" to the base form. For example, "He eats bananas everyday." The subject of the sentence is "he" which is singular. Therefore, the base form of the verb is added with an "-s" which is "eats".
