Explanation:

An adverb modifies a verb, adjective, or another adverb, often answering questions like how, why, when, or where. "To better augment" modifies the verb "added" and explains the purpose (why) of adding new personnel. "Of the company" is a pre - positional phrase modifying "administrator", "overseeing the department" is a present - participle phrase modifying "woman", and "existing sales force" is a noun phrase.

C. to better augment
