Answer

Brief Explanations:

In indirect observation, signs like tracks, nests are used instead of directly observing the population. So the population is unaware of the sampler's presence. In mark - recapture, animals are marked, in direct observation animals are directly seen, and in sampling, parts of the population are directly studied. These methods make the population aware.

Answer:

D. indirect observation
