Reveal answer & explanation
Correct answer: B) Quota sampling
Explanation
In quota sampling the interviewer chooses who to include until a set number in each category has been reached, so not every item has a known chance of selection; it is a non-random method. Simple random sampling gives every item an equal chance of selection, stratified random sampling selects randomly within each stratum, and systematic sampling selects every nth item after a randomly chosen starting point, so chance determines which items are picked in all three.
