Answer: 1. Pavo, Psittacula, Corvus

Key idea: Birds have a crop and a gizzard in the digestive tract.

Pavo (peacock), Psittacula (parrot) and Corvus (crow) are all birds, so option 1 is right. The other options mix in a chameleon, fish, amphibian, mammal and snake, none of which has these chambers.
