Quaternary ammonium compound is commonly used as a:

  1. disinfectant

  2. styptic

  3. fumigant

  4. deodorant

The correct answer is: disinfectant

Quaternary ammonium compound is a chemical commonly used as a disinfectant. This compound contains positively charged ions that are able to disrupt bacterial cell walls and membranes, ultimately destroying the microorganisms. This makes it an effective option for disinfecting and sanitizing various surfaces and objects. The other options, such as B styptic, C: fumigant, and D: deodorant, are all incorrect because they do not have the same properties as a disinfectant. A styptic is a substance used to stop bleeding, a fumigant is a gas used to kill pests, and a deodorant is used to mask or neutralize unpleasant odors. None of these options have the same ability to kill bacteria and other microorganisms as a disinfectant.
