B. stratified random sample.

Step-by-step explanation:

The Stratified sampling is a type of sampling method in which the observer divides the whole sample population in the different or the separate groups.

These separated different groups are known as strata.

And from these, probability sample also called as simple random sample is taken out from each group.
