Answer

To answer the question "Just after a blood-meal, a female Anopheles will have in its stomach," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Feeding Habits of Female Anopheles**:
- Female Anopheles mosquitoes are known to feed on the blood of humans and other animals. This feeding is essential for their reproductive process, as they require the nutrients found in blood to develop their eggs.

2. **Composition of Human Blood**:
- Human blood is composed of different types of cells, primarily red blood cells (RBCs), white blood cells (WBCs), and platelets, all suspended in plasma. RBCs are responsible for carrying oxygen, while WBCs are part of the immune system.

3. **Analyzing the Options**:
- **Option 1**: Only white blood corpuscles - This is incorrect because female Anopheles consume blood, which contains both RBCs and WBCs.
- **Option 2**: White and red blood corpuscles - This is correct because both types of cells are present in the blood that the mosquito ingests.
- **Option 3**: Only red corpuscles - This is incorrect as it ignores the presence of WBCs in the blood.
- **Option 4**: Coagulated blood - This is also incorrect because the blood is not coagulated immediately after feeding; it remains in liquid form.

4. **Conclusion**:
- After a blood meal, a female Anopheles will have both white blood corpuscles and red blood corpuscles in its stomach. Therefore, the correct answer is **Option 2**.

### Final Answer:
The correct answer is **Option 2: White and red blood corpuscles**.
