Some people claim that the theory of evolution violates the second law of thermodynamics, since that theory holds that order develops out of disorder, corresponding to a decrease in entropy. This claim
A. if incorrect, would mean that the theory of evolution must be true. B. is incorrect; the second law says only that the total entropy in a closed system increases. C. is correct, thereby disproving the theory evolution. D. None of these choices are correct
