Suppose that you want to estimate the proportion of students at your college

that attend at least one of the college's sports events.

which sampling plan will produce the most reliable results?

Bis the right answer

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

32.10 is the correct answer
