Explanation:

I believe this is the answer because the other answers don't seem to make sense in the context of this scenario

i think the answer is b.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
