C. 2,4 correct
D. 1,3 correct.

Answer

To solve the question regarding body coordination, we need to analyze each of the systems mentioned and determine their relevance to body coordination.

### Step-by-Step Solution:

1. **Identify the Systems**: We have four systems to evaluate:
- Nervous System
- Circulatory System
- Endocrine System
- Excretory System

2. **Evaluate the Nervous System**:
- The nervous system is responsible for controlling body movements and coordinating responses. It sends signals through nerves to different parts of the body, including the brain and spinal cord, which are crucial for body coordination.
- **Conclusion**: The nervous system is involved in body coordination.

3. **Evaluate the Circulatory System**:
- The circulatory system is primarily responsible for the circulation of blood and body fluids. It does not play a direct role in coordinating body movements or responses.
- **Conclusion**: The circulatory system is not involved in body coordination.

4. **Evaluate the Endocrine System**:
- The endocrine system produces hormones that regulate various body functions. It works in conjunction with the nervous system to coordinate bodily functions and responses, thus playing a role in body coordination.
- **Conclusion**: The endocrine system is involved in body coordination.

5. **Evaluate the Excretory System**:
- The excretory system is responsible for the removal of waste from the body. It does not have a role in coordinating body movements or responses.
- **Conclusion**: The excretory system is not involved in body coordination.

6. **Summarize Findings**:
- The systems that contribute to body coordination are:
- Nervous System (1)
- Endocrine System (3)
- The systems that do not contribute are:
- Circulatory System (2)
- Excretory System (4)

7. **Select the Correct Option**:
- Based on the evaluations, the correct systems that help in body coordination are the Nervous System and the Endocrine System. Therefore, the correct answer is option (d) 1,3 correct.

### Final Answer:
**(d) 1,3 correct**
