The correct answer is (A) Natural Gas.
Just as Mica is a Non-Metallic Mineral, Natural Gas is an Energy Mineral (source of energy).
The analogy tests knowledge of mineral classification. Mica is a non-metallic mineral; Natural Gas is an energy mineral (fossil fuel used for energy). Bauxite is a non-ferrous metal ore, Manganese is a ferrous mineral, and Platinum is a precious metal — none are energy minerals.
