A) to enrich.

Explanation: an infinitive is the basic form of a verb, without an inflection binding it to a particular subject or tense. It is preceded by the particle “to,” and can serve as an adjective, an adverb, or a noun. In the given sentence, the part that contains an infinitive is "to enrich" because it has the particle "to" followed by a verb.
