Options

A. `CH_(4)`
B. `N_(2)`
C. Ar
D. `O_(2)`

Answer

To solve the question "Besides CO₂, the other greenhouse gas is," we need to identify a greenhouse gas from the options provided. Let's go through the steps:

### Step-by-Step Solution:

1. **Understanding Greenhouse Gases**:
Greenhouse gases are substances in the atmosphere that can absorb and emit infrared radiation. This process is what leads to the greenhouse effect, which warms the Earth.

2. **Identifying Common Greenhouse Gases**:
The most common greenhouse gases include:
- Carbon Dioxide (CO₂)
- Methane (CH₄)
- Nitrous Oxide (N₂O)
- Fluorinated gases (like CFCs)

3. **Analyzing the Options**:
The question asks for a greenhouse gas other than CO₂. Among the common greenhouse gases listed, we can identify methane (CH₄) as a significant greenhouse gas.

4. **Conclusion**:
Therefore, the answer to the question is **Methane (CH₄)**.

### Final Answer:
Besides CO₂, the other greenhouse gas is **Methane (CH₄)**.
