Respuesta :

Answer:

D. cluster

Step-by-step explanation:

Convenience: Based on availability.

Systematic: The first element is sorted randomly, then the others follow a pattern.

Random: Each member of a sample has the same probability of being sorted.

Cluster: Each group is cluster, and when a cluster is sorted, every member of the group is sample. This is the correct answer.

Stratified: Population is divided into groups and then members from these groups are sorted.
