In order for the survey results to be representative of the larger population, the sample should contain important subgroups in the same proportions as they are found in the population. This ensures that the sample is not biased towards any particular subgroup and the results can be generalized to the larger population. The other options are incorrect as generalization accuracy depends on the representativeness of the sample and not on the way the sample is chosen or the size of the sample.
