- A Secretes digestive enzymes
- B Stores food temporarily before digestion
- C Grinds food with the help of a thick cuticular lining
- D Absorbs digested nutrients into the haemolymph
Correct answer: C. Grinds food with the help of a thick cuticular lining
Explanation: The gizzard, part of the foregut, has a thick cuticular lining that grinds ingested food into smaller particles. Food is temporarily stored in the crop before reaching the gizzard, while the hepatic caecae secrete digestive enzymes in the midgut.
