Mica is used in cooking utensils because it is a

  1. A
    good conductor of heat but bad conductor of electricity
  2. B
    bad conductor of heat but good conductor of electricity
  3. C
    good conductor of both heat and electricity
  4. D
    bad conductor of both heat and electricity

Solution & Step-by-step Explanation

Mica is a naturally occurring mineral that possesses a unique combination of physical properties: it is a good conductor of heat but a bad conductor of electricity.
This allows it to efficiently transfer thermal energy required for cooking while acting as an effective electrical insulator, which prevents electrical hazards in appliances like electric irons and specialized cookers.
