Simple random sampling is the only option given that involves choosing individuals at random and giving each individual an equal chance of being selected. This makes it a fair and unbiased method of sampling. Quota sampling involves selecting individuals based on predetermined quotas, and stratified random sampling involves dividing the population into strata and selecting individuals from each stratum, which can introduce bias. Volunteer sampling involves individuals self-selecting to participate, which can also introduce bias.
