D.

Answer 1

Okay, the most basic form of a verb is the infinitive: to walk, to run (in short, it must have "to").

"To" is a rather annoying thing because it can be a lot of things including my two pet grammatical peeves: an infinitive and a prepositional phrase.

The trick to figuring out what is-look at what follows "to."

If a verb follows to ("to walk"), then this is an infinitive (or, in some cases, an infinitive phrase) and IS NOT a prepositional phrase.

If there are some adjectives or articles and a noun (there must always be a noun for this particular scenario), then it is a prepositional phrase ("to the park").

Looking at your options, it looks like C is going to be your answer because it is the only one that has a "to+verb" structure included in the sentence.

Hope this helps :)
