Correct answer: C. Using a bacterial spore test

  • A. Using chemical indicator strip or pouch
  • B. Recording a temperature/ pressure readings from sterilizer guage
  • C. Using a bacterial spore test
  • D. Determining the ability of a sterilizer to kill the hepatitis B virus

Explanation

A bacterial spore test is the best practical indicator because resistant spores directly demonstrate whether the sterilisation process can destroy highly resistant organisms. Chemical indicators and gauge readings mainly show exposure to conditions, not guaranteed microbial killing.
