An example of a chemical agent used in sanitization is:

  1. Boiling water

  2. Steam under pressure

  3. Ultra-violet rays

  4. Quats

The correct answer is: Quats

Quats, or quaternary ammonium compounds, are a type of disinfectant commonly used in sanitization to kill viruses and bacteria. Boiling water (A) can help to sanitize objects or surfaces by killing microorganisms, but it is not a chemical agent. Steam under pressure (B) also uses heat to kill microbes, but it is not considered a chemical agent. Ultra-violet rays (C) can be used as a disinfectant, but it is not a chemical agent used specifically for sanitization purposes. Therefore, the best answer is D Quats.
