- Non-Metallic Minerals: These do not contain metal substances and are often used in industries like construction, ceramics, and chemicals.
Analyzing the Options
- (A) Mica: A non-metallic mineral known for its insulation properties in the electrical industry.
- (B) Bauxite: A metallic mineral; it is the primary ore used to produce Aluminum.
- (C) Granite: A non-metallic mineral, specifically a common type of igneous rock used in construction.
- (D) Potash: A non-metallic mineral primarily used in the manufacture of agricultural fertilizers.
Conclusion: Since Bauxite is a metallic mineral, the non-metallic minerals in the list are (A), (C), and (D).
