Stratified sampling is a probability sampling method that involves dividing the population into subgroups or strata based on some criteria and then drawing a sample from each subgroup proportionally to its size in the population. This ensures that each stratum is represented in the sample and reduces the sampling error.

A) Quota sampling is a non-probability sampling method that involves setting specific quotas for certain characteristics or groups of people and then selecting individuals to meet those quotas, regardless of their probability of being selected. This method can introduce bias and is not representative of the population as a whole.

B) Chunk sampling is not a known sampling method.

D) Judgment sampling is a non-probability sampling method that involves selecting participants based on the researcher's personal judgment or discretion. This method can introduce bias and is not representative of the population as a whole.
