Correct Answer: activated carbon


Solution : The correct option is activated carbon .

If the water smells bad, adding a few drops of lemon juice or activated charcoal can help neutralise the odour. Additionally, proper ventilation and regular cleaning of water sources can address the issue.

In many different applications, including the preparation of food and beverages, removing odours, and industrial pollution control, activated carbon is used to purify liquids and gases.
