  • I believe it's cluster sampling.
  • Answer: D. cluster

    Step-by-step explanation:

    A cluster sampling is a random sampling method in which a researcher splits the entire population into separate groups known as clusters.Then, he draw a random sample of clusters from the population.

    After this he performs his analysis on data from the sampled clusters.
