Help me identify prepositional phrase, verbal phrase, or clause?

I’m excellent with grammar and 100% sure about this answer.

is a prepositional phrase because it includes a preposition and its object. It relates “books” to “market” with the preposition “on.”

is a verbal phrase because it includes an infinitive “to be.” An infinitive is just one of the several kinds of verbal phrases.

is a clause because it contains a verb “gave” and the subject of that verb “he.” All clauses contain both a subject and a verb.

Prepositional Phrase: on the market (on is the preposition)

Clause: when he gave us the Bible, how to be a good friend

A verbal phrase must have a verb and a preposition in the phrase. “go out”, “take down”, etc.
