Correct Answer: Activated carbon
Solution : The correct option is Activated carbon.
Powdered activated carbon is the suggested remedy for tastes, and odours that are modest and sporadic. By adding powdered activated carbon to water, or using granular activated carbon in the water filter, bad tastes, and unpleasant odours can be eradicated. The way activated carbon functions is by a process called adsorption, in which the component responsible for the odour is trapped inside the activated carbon, and kept without affecting the size of the substance doing the adsorption.
