When doing research, sampling is a very important part of it. Sample selection refers to the process of selecting a subset of the population you want to study in such a way that this subset is representative of the whole population so the results obtained in the study can be generalized to the entire population.
In this example, we see that some professional organizations require that researchers make every effort to ensure that participants are representative of the population to which the study's results will be generalized. This has to do with the process of selecting a sample since researchers need a sample that will actually allow them to generalize the results. Therefore, the correct answer is a) sample selection.
