Simple random sampling, stratified random sampling, and cluster sampling all use random methods of selection. Simple random sampling selects individuals randomly from the entire population, stratified random sampling divides the population into strata and selects individuals randomly from each stratum, and cluster sampling divides the population into clusters and randomly selects entire clusters to sample from. Therefore, B is the best choice as it includes all the sampling plans that use random methods of selection.
