The answer would be option c. or the third option hope this helps
An adverbial phrase contains two in more words which take a syntactic function of modifying verbs, adjectives, or adverbs. Now it says in the question which "underlined group of words is an adverbial phrase," but the underlining does not seem to show up on here. It seems like in the last option, "almost anything" are two words that are modifying "buy." In my opinion, that would be the best option, however I still do not know which groups of words are underlined. I hope this helped you out!
