Consider the given statements
(a) integrated system in our body, coordinate all activities of the organs
(b) neural part of integrated system provides chemical integration
(c) endocrine part of integrated system provides organized connectivity for quick coordination

Options

A. (1) a and b are true ,c is false
B. 2) a is true , b and c are false
C. (3) a and c are true ,b is false
D. (4)c is true , a and b are false

Answer

To analyze the given statements about the integrated systems in our body, we can break down each statement step by step.

### Step-by-Step Solution:

1. **Understanding the Integrated System**:
- The integrated system in our body refers to the coordination between different systems, primarily the nervous system and the endocrine system.
- The nervous system uses electrical signals (neurons) for quick responses, while the endocrine system uses hormones for longer-lasting effects.

2. **Evaluating Statement (a)**:
- **Statement**: "Integrated system in our body coordinates all activities of the organs."
- This statement is **correct**. The integrated system, which includes both the neural and endocrine systems, indeed coordinates the activities of various organs to maintain homeostasis and respond to changes in the environment.

3. **Evaluating Statement (b)**:
- **Statement**: "Neural part of integrated system provides chemical integration."
- This statement is **incorrect**. The neural system primarily provides electrical signals and sensory information. Chemical integration is mainly the role of the endocrine system, which releases hormones into the bloodstream to regulate bodily functions.

4. **Evaluating Statement (c)**:
- **Statement**: "Endocrine part of integrated system provides organized connectivity for quick coordination."
- This statement is also **incorrect**. The quick coordination is a function of the nervous system due to its rapid signaling through neurons. The endocrine system, while organized, typically acts more slowly through hormonal signals.

5. **Conclusion**:
- Based on the evaluations, statement (a) is correct, while statements (b) and (c) are incorrect. Therefore, the correct answer is option 2, which states that only statement (a) is correct.

### Final Answer:
- The correct answer is that only statement (a) is true.
