Explanation:

To have a valid scientific sample for surveying religiousness in a town, the sample must be representative of the entire town's population. Option A (students in school) and C (people who go to church) are biased as they don't represent all residents. A random sample (B) and a sample reflecting the town's demographic makeup (D) ensure the sample is representative, allowing accurate generalization of results.

Answer:

B. A random sample of the town's population, D. A mix of participants that reflect your town's makeup
