Concept:Mica conducts heat well but does not conduct electricity.Explanation:Mica is used in cooking utensils because it allows heat to pass through evenly. It is a good conductor of heat. At the same time, it is an electrical insulator. This means it stops electric current from flowing. That makes mica safe for kitchen appliances. It prevents electric shocks. Other properties of mica, like its layered structure, are not relevant here. The key point for utensils is that it distributes heat efficiently while blocking electricity.Answer:Option A: good conductor of heat but bad conductor of electricity
