The correct answer is D. Conclusions need to be drawn from a large population. Sampling is the process of selecting a representative subset from a larger population to draw conclusions about that whole population.

Explanation

Sampling is the process of selecting a representative subset from a larger population to draw conclusions about that whole population. When a population is too large to study entirely (due to time, cost, or feasibility constraints), sampling allows analysts to gather data from a manageable subset and then infer conclusions about the broader group. Option A describes controlled data collection, not sampling. Option B describes automation/ETL processes. Option C describes surveying, which is a data collection method but not the defining reason for sampling itself.
