Which one of the following green house gases is a contributor due to incomplete combustion of coal and petroleum?

Options

A. Oxide of nitrogen
B. Methane
C. Carbon mono oxide
D. Carbon-di-Oxide

Explanation

To solve the question regarding which greenhouse gas is a contributor due to incomplete combustion of coal and petroleum, we can follow these steps:

### Step 1: Understand Combustion
- Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light. It can be complete or incomplete.

### Step 2: Define Complete Combustion
- In complete combustion, a hydrocarbon (like coal or petroleum) reacts with oxygen to produce carbon dioxide (CO2) and water (H2O). The general reaction can be represented as:
\[ \text{Hydrocarbon} + O_2 \rightarrow CO_2 + H_2O \]

### Step 3: Define Incomplete Combustion
- Incomplete combustion occurs when there is not enough oxygen available for the fuel to react completely. This results in the production of carbon monoxide (CO) instead of carbon dioxide. The reaction can be represented as:
\[ \text{Hydrocarbon} + O_2 \rightarrow CO + H_2O \]

### Step 4: Identify the Greenhouse Gases
- Greenhouse gases include carbon dioxide (CO2), methane (CH4), and carbon monoxide (CO). However, the question specifically asks about the gas produced from incomplete combustion.

### Step 5: Analyze the Options
- From the options provided:
- **Carbon Dioxide (CO2)**: Produced during complete combustion, not incomplete.
- **Methane (CH4)**: Not produced during combustion processes.
- **Carbon Monoxide (CO)**: Produced during incomplete combustion.
- **Oxides of Nitrogen**: Not directly related to the combustion of coal and petroleum.

### Step 6: Conclusion
- The greenhouse gas that is a contributor due to incomplete combustion of coal and petroleum is **Carbon Monoxide (CO)**.

### Final Answer
- The correct answer is **Carbon Monoxide (CO)**.
