Correct answer: D) Systematic sampling
Explanation
Systematic sampling selects items at a fixed interval (here 8,000 / 200 = every 40th) from a random start. Stratified sampling divides the population into groups and samples randomly within each one, cluster sampling selects whole groups, and quota sampling is non-random, with interviewers filling set quotas. Systematic sampling can be biased if the list has a pattern that matches the interval.
