Correct option is D
Purposive sampling, also known as judgmental sampling, is the correct answer. In purposive sampling, the researcher uses their judgment to select participants that are most appropriate for the research study. This method is often used when a limited number of people have expertise in the area being researched or when the researcher is interested in a specific subgroup within the population. Unlike random sampling methods, purposive sampling does not aim for a representative cross-section of the population, but rather focuses on specific characteristics or criteria deemed relevant to the research question.
Information booster: The other options—quota sampling, convenience sampling, and cluster sampling—are different sampling techniques with distinct characteristics and are not synonymous with judgmental sampling.
