Solution
The correct option is A Aves
Gizzard is the hind part of the stomach in birds, especially modified for grinding food. The crop is an out-pocketing of the esophagus. Swallowed feed and water are stored in the crop until they are passed to the rest of the digestive tract.
The gizzard has a thick muscular wall and may contain small stones, that function in the mechanical breakdown of seeds and other foods. In this sense, the gizzard is comparable to the teeth of other animals.
