Answer

To determine which part of the cockroach leg is attached to the thorax ventrally, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Cockroach Legs**:
- Cockroach legs are composed of five segments known as podomeres: coxa, trochanter, femur, tibia, and tarsus.

2. **Identify the Location of Each Segment**:
- The coxa is the first segment of the leg, connecting directly to the thorax.
- The trochanter follows the coxa, then comes the femur, tibia, and finally the tarsus.

3. **Focus on the Attachment Point**:
- The question specifies which part is attached to the thorax ventrally. The coxa is the segment that articulates with the thorax.

4. **Examine the Options Given**:
- The options provided are:
- A) Trochanter
- B) Claw
- C) Femur
- D) Coxa
- Since the coxa is the first segment and connects directly to the thorax, it is the correct answer.

5. **Conclusion**:
- The part of the cockroach leg that is attached to the thorax ventrally is the **coxa**.

### Final Answer:
The correct answer is **Coxa**.
