Shalu observed a strong smell of burning hair during a fire accident in her bedroom. Which of these objects could the fire have started from?

Options

A. Nylon rug
B. Silk curtains
C. Rayon towels
D. Cotton bedsheet

Explanation

To determine which object could have started the fire that Shalu observed, we need to analyze the situation step by step.

### Step 1: Identify the Smell
Shalu noticed a strong smell of burning hair. This indicates that the material that burned has a similar chemical composition or properties to hair.

### Step 2: Understand the Composition of Hair
Hair is primarily made of a protein called keratin. When it burns, it produces a distinct smell that is often described as similar to burning flesh or burning hair.

### Step 3: Consider Common Materials
We need to consider common materials found in a bedroom that could produce a similar smell when burned. Some materials that might be present include:
- Natural fibers (like wool or cotton)
- Synthetic fibers (like nylon or polyester)
- Other household items (like plastic)

### Step 4: Analyze the Options
1. **Wool**: This is a natural fiber and has a smell similar to burning hair when it burns.
2. **Nylon**: This is a synthetic fiber, and while it can burn, it does not produce a smell similar to burning hair.
3. **Cotton**: This is also a natural fiber but has a different burning smell compared to hair.
4. **Plastic**: This is synthetic and produces a very different smell when burned.

### Step 5: Conclusion
Given the options, the most likely object that could have started the fire, producing a smell similar to burning hair, is **wool**.

### Final Answer
The fire could have started from an object made of **wool**.
