The correct option is B Atavism
Atavism is the tendency to reappear some ancestral features like tail in the human foetus, colour blindness in humans, extra toe in horses etc., after several generations. Whereas anabolism is the process of formation of complex molecule by the use of energy, catabolism is the process of breakdown of complex molecule with the release of energy and metabolism is the combined process of anabolism and catabolism. Thus, the correct answer is option C.
