In which of the following sentences do you find a verb phrase?
a. i believed every word he said.
b. june was a collector of memorabilia.
c. i shall be all that i am and more.
d. the crowed roared as the bull charged.

Verb phrases are verbs that may function as a predicate, adjective, or adverb.

(a) "That he said" is an adjective modifying "word". However, this contains the s ubject"he" and the verb "said". It is a clause and NOT a phrase. Phrases can only have either a verb or a noun.
(b) There's only one verb "was" but it does not come with a complement, object, modifier, or other verb. Hence, it's NOT a verb phrase.
(c) "Shall be" consists of the modal shall and the be-verb be. This is a perfect example of a verb phrase that functions as a VERB PHRASE.
(d) "Roared" and "charged" are two verbs referring to different subjects. They do not come with a complement, object, modifier, or another verb. Hence, they're NOT a verb phrase. "As the bull charged" is a clause and not a phrase.

The answer then is C.
