An agent described as sporicidal is one that

  • A.removes spores by filtration
  • B.kills bacterial endospores
  • C.prevents spores from forming
  • D.stimulates spores to germinate

Answer: B

Killing the dormant spore is the hardest test a chemical agent faces, and only a few classes manage it: the aldehydes, ethylene oxide, strong oxidising agents and high-strength halogens. Preventing sporulation is a quite different matter.
