The correct answer is option C. all answers are sources of error.

Explanation:

The major source of error in any scientific experiment includes instrumental error which means that instruments or lab equipment are not accurate or calibrated properly or not able to determine the experiment.

It also includes a human or manual error in observing experiment observation or analyzing or calculating the results. Evolutionary errors are also one of the major sources of error that include humidity, temperature, wind, or light.

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.
