Which of the following is a correct way to conserve water?

Correct answer: Closing taps after use

Correct answer: A, closing taps after use. Water conservation means preventing avoidable loss and using available water carefully. When a tap is closed immediately after use, water does not continue flowing into the drain without a purpose. This simple habit is useful at home, school, and workplaces. B is incorrect because leaving water running while brushing wastes water even though brushing does not require a continuous flow. C is incorrect because a continuously running hose uses much more water than a controlled amount or a bucket. D is also not a good conservation choice when the leftover clean water could safely be reused, for example for watering plants or cleaning. Closing a tap does not solve every water problem, but it is a direct and practical conservation action. Memory cue: use only what is needed, then close the tap.
