Answer: B - The researcher is like to use stratified random sampling.
Stratified random sampling is used when the population of interest varies in terms of certain strata such as sex, age, and education that are relevant to the research question, and the investigator wants to make sure that each stratum is represented in their sample. Simple random sampling refers to situations where every member has an equal opportunity to get selected to a group.
