most people say that option B should be the ans but i think that option A is correct cause the question is about behavioural adaption . Option B, C, and D are based on body features but as for option A the hognose snake pretends to act as if it is dead ...that is an adaptional behaviour to attract it's prey towards it . so option a is correct.
