The correct option is C Huxley
Birds are glorified reptiles, this statement is given by Huxley. He classified reptiles and birds in the same group, Sauropsida. He reasoned that if birds had not been so outstandingly successful in their aerial adaptation and speciation and if they had remained a relatively small group like pterosaurs, they would now be regarded as an order of reptiles, not a separate class of vertebrates. Hence, option B is correct.
