c) Binomial distribution.

Step-by-step explanation:

A binomial distribution uses discrete variables, which represents whole numbers, like persons. Also, this type of distribution is used when only to events are possible: success or failure. In this case, success would be require repair, and failure not require repair.

Binomial distribution is also characterised by having a fixed probability k about the success occurrence between trials, which is 0.025 in this case.
