Option (B) Bauxite is correct. According to the textbook, one mode of mineral formation involves the decomposition of surface rocks and the removal of soluble constituents. This process leaves behind a residual mass of weathered material containing ores. The textbook explicitly states that Bauxite is formed this way. The other options are incorrect: Coal is formed in sedimentary rocks as a result of deposition and concentration under heat and pressure, while Zinc occurs in veins and lodes in igneous and metamorphic rocks.
