Solution
Sol. [Key Concept: Cockroach alimentary canal]
Crop stores food (A–IV). Gastric caeca are the six to eight blind tubules at the foregut–midgut junction and secrete digestive juices (B–II). Malpighian tubules are the numerous yellowish excretory tubules at the midgut–hindgut junction (C–III). Gizzard grinds food (D–I). Hence, option (3).
