B. They are bad conductors of electricity.
C. They are good conductors of heat.
D. They are bad conductors of heat.

Answer

To answer the question of why metals such as copper, iron, and aluminum are used to make kitchen utensils, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Properties of Metals**:
- Metals are known for their physical properties, which include conductivity, malleability, ductility, and strength.

2. **Focus on Conductivity**:
- Among the properties, conductivity is particularly important when it comes to cooking. Metals are good conductors of both heat and electricity.

3. **Importance of Heat Conductivity in Cooking**:
- In the context of kitchen utensils, heat conductivity is crucial. Good conductors of heat allow for even cooking and efficient transfer of heat from the stove to the food.

4. **Evaluate the Metals in Question**:
- Copper, iron, and aluminum are all excellent conductors of heat. This means they can quickly transfer heat, making them ideal for cooking.

5. **Conclusion**:
- Therefore, the primary reason metals like copper, iron, and aluminum are used to make kitchen utensils is that they are good conductors of heat, which facilitates effective cooking.

### Final Answer:
Metals such as copper, iron, and aluminum are used to make kitchen utensils because they are good conductors of heat.
