AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Mica is widely used in electrical and electronics industries because of its excellent dielectric strength, low power loss factor, insulating properties, and resistance to high voltage.

The question asks for one reason, but the passage lists these properties together as a combined reason. In the exam, stating any one property (e.g., "excellent insulating properties" or "resistance to high voltage") is sufficient for 1 mark. Mentioning the full set is also acceptable and safe.
