Solution
The correct answer is (d).
Crop and gizzard are part of the digestive tract of birds (class Aves) and insects (phylum Arthropoda). Pavo, Psittacula, Corvus are birds hence all three have crops and gizzard. Chameleon, Bangarus and Crocodilus are reptiles and reptiles do not have crop and gizzard in their digestive system. Bufo belongs to class Amphibia and Balaenoptera is a mammal.
