    1. Please see:
      B and C options can be considered on the deduction that the animal is a poikilotherm and hibernating or some such thing.
      Where does the question say this ?
      If we have to make a deduction then it shud be rather said that the animal is a mammal and the response in mammals is an increase in symapthetic activity and an increases in TRH (increase in TRH is doubtful in humans)

      So the answer still stands out to be A.
      Also ask your friend that if Option B is correct then why not option C too ?
