• D. None of the above

Answer 1

The correct option is A Increase in concentration of a toxic substance as they go up the trophic level

Biomagnification is a process by which a toxic non-biodegradable substance increases in concentration as it goes up the trophic level. These substances tend to reside in the body of organisms forever, and get accumulated in a much higher concentration in organisms that feed on the former, and so on.
