B)Poisson distribution.
C)hypergeometric distribution.
D)none of the above.

The scenario described fits the description of a binomial distribution, where there are a fixed number of trials (125 computers), each trial can result in one of two outcomes (require repair or not require repair), the probability of success (requiring repair) is constant (0.025), and the trials are independent of each other. The question specifically asks for the probability of exactly 20 of the computers requiring repair, which is the type of scenario that can be solved using the binomial distribution formula.
