Suppose the state decides to randomly test high school wrestlers for steroid use. There are 16 teams in the league, and each team has 20 wrestlers. State investigators plan to test 32 of these athletes by randomly choosing two wrestlers from each team. Is this a simple random sample?

A. Yes, because the wrestlers were chosen at random.
B. No, because not all possible groups of 32 wrestlers could have been the sample.
C. Yes, because stratified samples are a type of simple random sample.
D. No, because a random sample of teams was not first chosen.
E. Yes, because each wrestler is equally likely to be chosen.
