**Explanation:**
Mica is a naturally occurring mineral that has several unique properties, making it suitable for various applications. In the case of electrical appliances, mica is used as an insulating material rather than a conducting material. Let's understand why option 'A' is the correct answer.
**1. Mica as a conductor of heat:**
Mica is an excellent conductor of heat. It has a high thermal conductivity, meaning it can efficiently transfer heat from one point to another. This property of mica makes it useful in electrical appliances such as electric irons, where heat needs to be evenly distributed across the heating element to ensure efficient ironing.
**2. Mica as a conductor of electricity:**
Contrary to its excellent thermal conductivity, mica is a poor conductor of electricity. It is an electrical insulator, which means it does not allow the flow of electric current through its structure. This property is crucial in electrical appliances to prevent short circuits or electric shocks. By using mica as an insulating material, the risk of electrical mishaps is reduced.
**3. Importance of using a good conductor of heat but a bad conductor of electricity:**
In electrical appliances like electric irons, it is essential to have a material that can efficiently conduct heat to the ironing surface while simultaneously insulating against the flow of electricity. If mica were a good conductor of electricity, there would be a higher risk of short circuits or electric shocks when using the electric iron. Therefore, it is necessary to use a material like mica, which is a good conductor of heat but a bad conductor of electricity.
**Conclusion:**
Mica is used in electrical appliances such as electric irons because it possesses the property of being a good conductor of heat but a bad conductor of electricity. This combination allows for efficient heat transfer while providing electrical insulation, reducing the risk of electrical mishaps.

Mica is an insulator so it doesn't conduct electricity but it absorbs heat. Therefore mica is a good conductor of heat.
