When conducting a population sampling study, on the first capture attempt, we tag, count, and release the captured individuals. Thus, option "D" is correct.
<h3>What is the mark-recapture method?</h3>
This is a method commonly used in ecology to estimate the animals in the population. A portion of the population is captured, marked and released. Another part of the population will, later on, be captured. This can be used to estimate the population in an assumption that the portion that was captured is proportional to the entire population. This is obtained by dividing the number of marked individuals by the individual marked on the second capture. This is one of the simplest and most practical methods of estimating the population.
Thus, option "D" is correct.
