Using sampling concepts, it is found that the sentence is:
C. If a population is all actors, a sample of the population could be movie actors.
A sample is a group taken from the population. It has to come from a more restrict group of the population, that is, an subset of the population.
In option A, baseball players is a subset of all athletes, so all athletes would be the population and baseball players would be the sample. The same can be applied in options B and D.
In option C, movie starts is a subset of all actors, thus the roles of sample and population are correct.
