A. In crop
B. In Gizzard
C. In mesenteron
D. In oesophagous

Answer

**Step-by-Step Solution:**

1. **Understanding the Digestive System of Cockroach**: The cockroach has a complex digestive system that consists of several parts, including the foregut, midgut, and hindgut.

2. **Identifying the Parts of the Digestive System**:
- **Foregut**: This includes the mouth, pharynx, esophagus, and gizzard. The gizzard is responsible for grinding food.
- **Midgut**: This is the region that follows the gizzard and is primarily responsible for digestion and absorption.
- **Hindgut**: This part is mainly involved in the absorption of water and the formation of feces.

3. **Focusing on the Midgut**: The midgut, also known as the mesenteron, is lined with enzyme-secreting tissues. It is the main site for digestion and absorption of nutrients.

4. **Role of the Midgut**: The midgut contains structures called the hepatic caeca (or enteric caeca) that secrete digestive enzymes. These enzymes help in breaking down food, which is then absorbed through the walls of the midgut into the surrounding space known as haemolymph.

5. **Conclusion**: Based on the functions of the digestive system parts, it is concluded that the maximum digestion in a cockroach takes place in the **midgut**.

**Final Answer**: The maximum digestion takes place in the **midgut** of the cockroach.
