If someone wants to ask a question that doesn't have a lot is variability, which answer should it be?

a. do you like soccer, baseball, or football?
b. have you watched the sports on tv?
c. what is your fave sport?
d. do you own a glove?

i picked "d" because it was a simple answer that didn't yield variability. , all of them doesn't have if you answer the 4 questions it's only 1 answer. not multiple.
*i actually attempt and do my homework*
