What is sampling?

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, the population only has right-handers, hence the sample will also have only right-handers. However, all types of right-handers have to be selected, including those with brown hair, hence excluding them is selection bias and option D is correct.
