ANS: A
Quota sampling uses a convenience sampling technique with an added feature, a strategy to ensure the inclusion of subject types or strata in a population that are likely to be underrepresented in the convenience sample, such as women, minority groups, the elderly, the poor, the rich, and the undereducated. This method may also be used to mimic the known characteristics of the target population or to ensure adequate numbers of subjects in each stratum for the planned statistical analyses. The technique is similar to that used in stratified random sampling but the initial sample is not random.
