Breathing is a process that
(i) provides `O_(2)` to the body
(ii) breaks down food to release energy
(iii) helps the body to get rid of `CO_(2)`
(iv) produces water in the cells.
Which of the following gives the correct combination of functions of breathing?

Options

A. (i) and (ii)
B. (ii) and (iii)
C. (i) and (iii)
D. (ii) and (iv)

Explanation

To solve the question regarding the functions of breathing, we will analyze each statement provided and determine which ones are correct.

### Step-by-Step Solution:

1. **Understanding Breathing**:
- Breathing is primarily the process of gas exchange in the body. It involves taking in oxygen (O₂) and expelling carbon dioxide (CO₂).

2. **Analyzing Statement (i)**:
- **Statement (i)**: "Provides O₂ to the body."
- This statement is correct because breathing allows oxygen to enter the lungs, which is then transported to the cells of the body.

3. **Analyzing Statement (ii)**:
- **Statement (ii)**: "Breaks down food to release energy."
- This statement is incorrect. The breakdown of food to release energy is part of cellular respiration, which is different from the act of breathing itself.

4. **Analyzing Statement (iii)**:
- **Statement (iii)**: "Helps the body to get rid of CO₂."
- This statement is correct. During breathing, carbon dioxide produced by cellular metabolism is expelled from the body.

5. **Analyzing Statement (iv)**:
- **Statement (iv)**: "Produces water in the cells."
- This statement is incorrect. While water is produced as a byproduct of cellular respiration, it is not a direct function of breathing.

6. **Conclusion**:
- The correct functions of breathing are represented by statements (i) and (iii). Therefore, the correct combination of functions of breathing is option 3, which includes statements 1 and 3.

### Final Answer:
The correct combination of functions of breathing is **(i) and (iii)**.
