A) defensive adaptation of skin against UV radiations
B) drug resistance
C) protective resemblance with the surrounding
D) darkening of skin due to industries
Correct Answer: C
Solution :

The mutant dark forms of insects (eg, Biston betularid) would not be easily seen and avoid being preyed due to protective resemblance with the surrounding, while light coloured forms are easily seen by predators and preyed easily.
