D)antisepsis.

Accepted Answer

Sterilization is the only term that specifically refers to the complete elimination of all microorganisms, including viable spores. Disinfection refers to reducing the number of pathogenic microorganisms, but not necessarily eliminating all of them. Sanitation refers to the reduction of microbial populations to safe levels, and antisepsis refers to the use of antimicrobial agents on living tissue to prevent infection.
