Options

A. Covering utensils while cooking
B. Switching off lights and fans when not is use
C. Using public transport and bicycles for travelling
D. Using conventional bulbs instead of CFLs and LEDs

Answer

To determine which practices can lead to the wastage of fuels, we need to analyze the different scenarios mentioned in the transcript. Here’s a step-by-step solution:

### Step 1: Identify the Practices
We need to list the practices mentioned in the transcript:
1. Covering utensils while cooking
2. Switching off lights and fans
3. Using public transport
4. Using conventional bulbs

### Step 2: Analyze Each Practice
Now, let’s analyze each practice to see if it leads to fuel wastage:

1. **Covering utensils while cooking**:
- This practice helps retain heat and cook food faster, which saves energy.
- **Conclusion**: Not a wastage of fuel.

2. **Switching off lights and fans**:
- Turning off lights and fans when not in use conserves energy and reduces fuel consumption.
- **Conclusion**: Not a wastage of fuel.

3. **Using public transport**:
- Public transport allows multiple people to travel together, which is more efficient and reduces individual fuel consumption.
- **Conclusion**: Not a wastage of fuel.

4. **Using conventional bulbs**:
- Conventional bulbs consume more power compared to energy-efficient options like LED and CFL bulbs. This higher consumption can lead to wastage of fuel.
- **Conclusion**: This is a wastage of fuel.

### Step 3: Final Conclusion
Based on the analysis, the practice that leads to wastage of fuels is:
- **Using conventional bulbs**.

### Summary
The only practice that can lead to wastage of fuels is using conventional bulbs. All other practices mentioned (covering utensils, switching off lights and fans, and using public transport) contribute to saving energy and fuel.
