Unburnt carbon particles of the fuel cause

Options

A. stomach infections
B. respiratory problems
C. brain infections
D. skin problems

Explanation

**Step-by-Step Solution:**

1. **Understanding Unburnt Carbon Particles:**
- Unburnt carbon particles are residues that result from the incomplete combustion of fuels. When fuels do not burn completely, they release carbon particles into the atmosphere.

2. **Identifying the Source of Unburnt Carbon:**
- These particles are produced during the process of incomplete combustion. This can occur in various situations, such as in engines, fireplaces, or during industrial processes where fuel is not burned efficiently.

3. **Effects of Unburnt Carbon Particles:**
- Unburnt carbon particles are considered dangerous pollutants. They can have serious health implications for humans, particularly affecting the respiratory system.

4. **Health Implications:**
- Exposure to unburnt carbon particles can lead to respiratory problems. One common respiratory disease associated with this exposure is asthma. Asthma is characterized by difficulty in breathing, wheezing, and coughing.

5. **Conclusion:**
- Therefore, unburnt carbon particles from incomplete combustion of fuel can cause respiratory problems, making them a significant environmental and health concern.
