Which of the following is not a green house gas ?

Options

A. Methane
B. Carbon dioxide
C. Carbon monoxide
D. Ammonia

Explanation

To determine which of the following is not a greenhouse gas, we can follow these steps:

### Step 1: Understand what greenhouse gases are
Greenhouse gases are gases that absorb and emit radiant energy within the thermal infrared range. This process contributes to the greenhouse effect, which warms the Earth's surface.

### Step 2: Identify common greenhouse gases
Common greenhouse gases include:
- Carbon Dioxide (CO2)
- Methane (CH4)
- Nitrous Oxide (N2O)
- Carbon Monoxide (CO)

### Step 3: Analyze the options provided
We need to look at the options given in the question and identify which one is not a greenhouse gas.

### Step 4: Evaluate each option
- Methane: This is a greenhouse gas.
- Carbon Dioxide: This is also a greenhouse gas.
- Carbon Monoxide: This is a greenhouse gas.
- Ammonia (NH3): This is not typically classified as a greenhouse gas.

### Step 5: Conclude the answer
Based on the analysis, the gas that is not a greenhouse gas is **Ammonia**.

### Final Answer:
The correct answer is **Ammonia**.
