Concept:Mica is a mineral with high electrical resistance and thermal stability.
Explanation:Mica has excellent dielectric strength. It can withstand high voltages without breaking down.
This property makes it ideal for use in capacitors, transformers, and insulating sheets.
Mica also resists heat and acts as a good thermal insulator.
These features are essential in electrical and electronic components.
Mica is not suitable for food, beverages, iron, steel, or aluminium processing.
It does not have the required properties for those industries.
Therefore, mica is primarily used in electrical and electronic industries.
Answer:D. electrical and electronic industries.
