# Brief Explanations:
To get an unbiased sample for determining popular stores, the sample should represent all mall - goers. Surveying people at one store (A) is biased as it only represents customers of that store. Surveying employees (B) is biased as they may have different opinions than customers. Studying revenue (D) doesn't directly measure popularity among customers. Surveying people from various locations in the mall (C) gives a more representative sample of all mall - goers.
