ANS:A - Mineral oils

Among the options provided, mineral oils typically have the least oiliness. Mineral oils are derived from petroleum sources through processes such as distillation and refining. They are often used as lubricants, hydraulic fluids, and in various industrial applications due to their low cost, stability, and consistent performance characteristics. In contrast, vegetable oils, greases, and animal oils may exhibit higher levels of oiliness due to their natural origins and compositions. These types of oils and greases may contain higher levels of fatty acids and other organic compounds that contribute to their lubricating properties.
