Answer:
The answer is indeed letter A) He knew some salsa would add kick.
Step-by-step explanation:
We are looking for a sentence that presents figurative language. When an author uses figurative language, he/she employs words in a different way, by giving them meanings that are not the literal and obvious meanings they carry. There are many devices to use figurative language, the most common beings metaphors, similes, hyperboles etc.
From the sentences that we can choose, the very first one uses figurative language when it employs the word "kick" with a meaning that is not its orginal one. Kick, be it as a verb or as a noun, usually describes the action of hitting something with your foot. But, by saying that salsa would add a kick to the dish, the author means salsa would give it more of a strong flavor. Therefore, because kick was not used in its original sense, I believe letter A to be the best choice.
