For the survey results to be considered valid, the correct statement is:
**The sample must represent the target population.**
This means that the characteristics of the sample should closely match those of the larger population you are trying to learn about. The other options provided are not necessary for a valid survey: the sample does not have to be the same size as the population, it should ideally be unbiased, and it does not need to be a separate group from the population.
