B. Use only personal vehicles for travelling
C. Cook food in open utensils on high flame
D. Switch off electronic appliances when not in use

Answer

To answer the question "Which of these should you do to conserve energy?", we need to evaluate each option provided and determine which action would help in conserving energy.

### Step-by-Step Solution:

1. **Evaluate the First Option: Keep Air Conditioners On**
- Keeping air conditioners on continuously consumes a significant amount of energy. This is not a method of conserving energy.
- **Conclusion**: This option does not help in energy conservation.

2. **Evaluate the Second Option: Use Only Personal Vehicles for Travelling**
- Using personal vehicles for travel leads to higher fuel consumption compared to public transportation. Public transport can accommodate more people, thus reducing the overall energy used per person.
- **Conclusion**: This option is not effective for conserving energy.

3. **Evaluate the Third Option: Cook Food in Open Utensils on High Flame**
- Cooking food on a high flame in open utensils wastes energy as it can lead to heat loss and inefficient cooking. It is not a method of conserving energy.
- **Conclusion**: This option does not contribute to energy conservation.

4. **Evaluate the Fourth Option: Switch Off Electronic Appliances When Not in Use**
- Switching off electronic appliances when they are not in use is a direct way to conserve energy. It prevents unnecessary energy consumption and helps reduce electricity bills.
- **Conclusion**: This option is the best choice for conserving energy.

### Final Answer:
The correct action to conserve energy is to **switch off electronic appliances when not in use**.
