B Correct answer
Explanation

Biological magnification (or biomagnification) refers to the increasing concentration of non-biodegradable substances like pesticides, mercury, or heavy metals at each successive trophic level in a food chain. Substances accumulate in higher concentrations as you move up. Food web is the feeding network, decomposition is breakdown, and fermentation is a microbial process.
