Solution
The correct option is C Gizzard Birds have adaptations which aid them in flight such as-
hollow air-filled bones (pneumatic bones)
lungs associated with air sacs to increase efficiency of respiration
wings for flight
The gizzard is a part of the digestive system in birds. It functions like a grinding mill. It is the organ where food is broken down into smaller units.
Crop is a pouch in the esophagus where food is stored temporary before moving into the stomach.
