Bad or offensive breath is treated by gargling with?

Water
Perfumed water
Formalin
An antiseptic

The correct answer is: An antiseptic

Gargling with an antiseptic solution, such as mouthwash, effectively kills bacteria in the mouth that cause bad breath. Water and perfumed water may temporarily mask the odor but do not address the root cause. Formalin, a liquid containing formaldehyde, should not be ingested and is not safe for gargling without medical supervision. Additionally, using an antiseptic specifically designed for oral care is more effective and safer than formalin for treating bad breath.
