Reveal answer & explanation
Correct answer: B) Stratified sampling samples *some* members from *all* groups, while cluster sampling samples *all* members from *some* (randomly selected) groups.

Cluster sampling is typically more cost-effective for geographically dispersed populations, as the researcher focuses on entire random 'clusters' rather than selecting individuals across every group.
