Correct answer: A
The digestive system of a cockroach consists of several specialized structures that perform specific functions:
- Crop is a part of the alimentary canal where food is stored temporarily. This aligns with the description for List I "A. The structures used for storing of food". Thus, A corresponds to IV (Crop).
- Gastric Caeca are blind tubules located at the junction of the foregut and the midgut in insects. These tubules secrete enzymes and provide an increased surface area for digestion and absorption. This fits the description for List I "B. Ring of 6-8 blind tubules at junction of foregut and midgut". Hence, B corresponds to II (Gastric Caeca).
- Malpighian tubules are thin filamentous structures present at the junction of the midgut and hindgut. They are primarily involved in excretion and osmoregulation. They match the description for List I "C. Ring of 100-150 yellow coloured thin filaments at junction of midgut and hindgut". Thus, C corresponds to III (Malpighian tubules).
- Gizzard, also known as the proventriculus, is equipped with hard chitinous plates that grind the food mechanically. This description fits List I "D. The structures used for grinding the food". Therefore, D corresponds to I (Gizzard).
By collaborating all this information, the correct answer is:
Option A: A-IV, B-II, C-III, D-I
