Answer:
0.0018 = 0.18% probability of two out of tree people having a reaction.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have a reaction, or they do not. The probability of a person having a reaction is independent of any other person. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
The probability of someone having a reaction to a medication is 0.025.
This means that 
What is the probability of two out of tree people having a reaction?
This is
when
. So


0.0018 = 0.18% probability of two out of tree people having a reaction.
C seems like the most mathematically correct answer. If baseball season started in April, the April results aren't going to be statistically meaningful, because it is such a small time-frame. However, at the end of the season, there is a lot more data so that an average can be accurately calculated for each player, and this average is likely going to be closer to their lifetime average.
