B. verb phrase
I know this verb phrase consists of an auxiliary, or helping verb, and a main verb. The helping verb always precedes the main verb.
Helping verbs include forms of be, such as am, is, are, was, were, being, and been; forms of have, such as has and had; forms of do, such as does and did; forms of can, such as could, will, would, and shall; and forms of should, such as may, might, and must.
