Which statement about disinfectants is accurate?

• A. They must be hypoallergenic
• B. They must be effective against microbes
• C. They must be used without gloves
• D. They must be edible

Answer: (B)

Disinfectants are chemical agents used to kill or inactivate microorganisms on surfaces, helping prevent the spread of infection. The essential point is that they must be proven to be effective against microbes; without that antimicrobial activity, a product isn’t fulfilling the purpose of disinfection. That’s why the statement that they must be effective against microbes is the accurate one.

Disinfectants aren’t defined by being hypoallergenic or edible, and they’re not typically used without protective gloves—gloves are commonly worn to protect skin from irritation or chemical burn during handling.
