Answer:
adverb phrase
B: the best salsa; modifies make
Explanation:
The phrase "almost every day" is an adverb phrase. This type of sentence has the same function as adverbs, which is to modify a verb (or another grammatical class) by emphasizing and imposing a characteristic on the verb. In the case of the phrase "almost every day" we can see that the verb "exercised" has been modified according to time.
The same occurs with the phrase "Tomatoes from the garden make the best salsa," where the phrase "the best salsa" takes the place of adverb and modifies the verb "make" as a function of mode.
