Item (D)
Step-by-step explanation:
In the stratified random sample we would divide our population into homogeneous groups / strata and then we randomly select the individuals in each group / stratum.
In general, when comparing with the simple random sample, we realize that stratified random sampling has the advantage of increasing accuracy and decreasing variability.
In the question, we have two strata: female students and male students. On each one of the strata, a random sample of 25 names was made in the list.
