Solution
The correct option is D Purifiers Sedimentation is the process which allows particles in water to settle down. Sedimentation technique does not purify water such that it is fit for consumption.
Boiling is one of the oldest methods to clean water.
Bleach is used to clean large amounts of water.
Purifiers are the device which cleans the water and it is the most convenient purification method. Since we need to purify drinking water in large quantities, purifiers are the best option.
