Explanation:

An infinitive phrase is a group of words, as part of a sentence in most cases, with the purpose of acting like an adverb, a noun or an adjective. This group of words makes use of the infinitive form ( to + verb-go in this case ) so as to express the action.

To express the action, the infinitive applies an affect on an object or a modifier ( adjective or adverb-quickly )

The first option contains an infinitive form but does not have an effect on an object or a modifier.

The last option is a prepositional phrase as it expresses location.
