Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The word adsorb is important here. When a material adsorbs something, it attaches to it by chemical attraction. The huge surface area of activated charcoal gives it countless bonding sites. When certain chemicals pass next to the carbon surface, they attach to the surface and are trapped. This means that an activated charcoal filter will remove certain impurities while ignoring others.
