A) Reducing agents cause reduction and are themselves oxidized. Bleaching powder’s action is primarily oxidation, not reduction. Therefore, it is used as an *oxidizing* agent, not a reducing agent. This statement is NOT true.
B), C), and D) are correct uses of bleaching powder. It is widely used as a bleaching agent for materials like wood pulp and textiles (linen) and as a disinfectant for water supplies and surfaces.
