Solution (By Examveda Team)
Probability sampling methods give every member of the population a known and non-zero chance of being selected.Simple random sample (Option A) is a probability sampling method because each individual has an equal and known chance of selection.
Quota sampling (Option B) is a non-probability sampling method. Researchers divide the population into subgroups and then use non-random methods to fill quotas for each subgroup.
Purposive sampling (Option C) is also a non-probability method, where participants are selected intentionally based on specific characteristics relevant to the research.
Therefore, both Quota sample and Purposive sample are non-probability samples.
Hence, the correct answer is D: Both B and C
