Cluster sampling is beneficial for when the target population is geographically dispersed. It involves dividing the population into clusters or geographical regions, and then randomly selecting a subset of these clusters to be included in the sample. This is more efficient than attempting to survey the entire population, particularly in cases where travel is difficult or expensive. Therefore, option A is the best choice. Options B and C do not necessarily require cluster sampling, as household interviews and mail surveys can be done using other sampling techniques. Option D also does not require cluster sampling, as experimental research typically involves a different sampling approach.
