The right option is; D) crystalline structure
A mineral is a naturally occurring, inorganic (not produced by an organism) solid substance, that has a specific crystalline structure and chemical composition. All minerals have definite chemical constituents that differ within a specific limited range. The physical properties of minerals such as color, solubility, streak, hardness, luster, specific gravity, cleavage, are used in identifying them. Examples of minerals include halite, talc, galena and diamond.
