Are spores destroyed by disinfection?

  1. Yes

  2. No

  3. Only with alcohol

  4. Only with bleach

The correct answer is: No

Disinfection is the process of killing or removing harmful bacteria and microorganisms. While all disinfectants have varying levels of effectiveness, they are designed to target and destroy spores as well. Therefore, the statement "no" is the most accurate answer as all spores cannot be destroyed by disinfection alone. Option A is incorrect because not all spores can be destroyed by disinfection. Option C is incorrect because alcohol is not the only disinfectant that can destroy spores. Option D is incorrect for the same reason as option C.
