(c) Snake
Explanation:
Biomagnification is phenomenon of increasing concentration of a compound in the tissues of chain, usually as a result of food intake. In this case, the concentration of compound increases with increasing trophic level.
Pollutant increases in concentration from Producers → Primary consumers → Secondary consumers → Tertiary consumers → Top consumer. In the given question, only snake represents the tertiary consumer, so the concentration of DDT will be highest in snake.
