Explanation
★The time frame during which a study explores a situation is the reference period, so that is the answer.
★The reference period fixes the span of time to which the study's data and findings refer.
★So it marks the stretch of time within which the situation or problem is examined.
★Age is a characteristic of the subjects, not the time frame of the study.
★Longitudinal describes a study that follows subjects over a long time, a type of design, not the frame itself.
★Retrospective time looks back at the past, so the time frame of exploration is the reference period.
