Given the task definition, example input & output, solve the new input case.
You are given a sentence, a question and two answer options ('A' and 'B'). Your task is to find the correct answer (return the string of the correct option, not 'A' or 'B') for the given question.
Example: Sentence: Jacob and Benny are squatting at the gym. Jacob has thin frail legs and Benny has big strong legs. Question: Who squats less weight? (A) Jacob (B) Benny
Output: Jacob
Typically, people with thin frail legs squat less weight than people with big strong legs, so the answer is Jacob.
