A large quantity of one of the following is removed from our body by lungs.

Options

A. `CO_(2)` only
B. `H_(2)O` only
C. `CO_(2)` and `H_(2)O`
D. Ammonia

Explanation

**Step-by-Step Solution:**

1. **Understanding the Role of Lungs**: The lungs are primarily involved in the process of respiration, which is crucial for gas exchange in the body.

2. **Identifying the Process of Respiration**: During respiration, glucose and oxygen are utilized to produce energy. The chemical reaction can be summarized as:
\[ \text{Glucose} + \text{Oxygen} \rightarrow \text{Carbon Dioxide} + \text{Water} + \text{Energy} \]

3. **Recognizing Waste Products**: The main waste products of this process are carbon dioxide (CO₂) and water (H₂O). However, the focus here is on which of these is removed in large quantities by the lungs.

4. **Determining the Excretory Function of Lungs**: The lungs expel carbon dioxide as a waste product of respiration. This gas is produced in large amounts and needs to be removed from the body to maintain pH balance and prevent toxicity.

5. **Evaluating the Options**:
- **Option 1: Carbon Dioxide only** - This is correct, as carbon dioxide is indeed removed by the lungs.
- **Option 2: Water only** - Incorrect, as water is not primarily removed by the lungs.
- **Option 3: Carbon Dioxide and Water both** - Incorrect, since while both are products of respiration, only carbon dioxide is expelled by the lungs.
- **Option 4: Ammonia** - Incorrect, as ammonia is a nitrogenous waste excreted primarily through urine, not by the lungs.

6. **Conclusion**: The correct answer is that a large quantity of carbon dioxide is removed from our body by the lungs.

**Final Answer**: Carbon Dioxide only.
