Which method is the only type of cleaning that will kill bacterial spores?

Disinfection
Sanitation
Steam cleaning
Sterilization

The correct answer is: Disinfection

Disinfection is the correct method because it is the only option that specifically targets bacterial spores, which are highly resistant to other methods of cleaning. While sanitation and steam cleaning may reduce the number of bacteria present, they do not guarantee the elimination of bacterial spores. Sterilization is a more intense form of disinfection and may also be effective in killing spores, but it is not the only method to do so. Therefore, disinfection is the most appropriate and effective method for killing bacterial spores.
