Mineral oil is typically used as the base for insulating oil. Mineral oil belongs to which category?

Explanation:
Mineral oil is a hydrocarbon oil. It’s derived from crude oil and consists mainly of carbon–hydrogen molecules such as alkanes and related hydrocarbons. This nonpolar composition gives it excellent dielectric strength, thermal stability, and chemical stability, making it a reliable insulating base in electrical equipment. Alcohols, being polar and containing hydroxyl groups, would conduct electricity more readily and attract moisture, so they’re unsuitable as insulating oil. An aqueous solution is water-based and conducts electricity, which would compromise insulation. Silicone oil is a different class of insulating liquid based on siloxanes, not mineral (hydrocarbon) oil. So, mineral oil fits squarely in the hydrocarbon oil category.
