Bleaching powder releases chlorine gas, which acts as a disinfectant. When added to water, bleaching powder releases chlorine gas, which is a strong disinfectant. Chlorine gas reacts with organic matter, bacteria, and viruses in the water, killing them and making the water safe to swim in. Hence option A is the correct answer.

Option (B) is incorrect because while bleaching powder does react with organic matter in the water, it is the chlorine gas that is released that kills the bacteria and viruses. Hence option B is incorrect.

Option (C) is incorrect because bleaching powder does not react with minerals in the water. Hence option C is incorrect.

Option (D) is incorrect because bleaching powder does not raise the pH of the water. Hence option D is incorrect.
