In the modern safety match industry, the striking surface of the matchbox and the match head contain specific chemical compositions to prevent accidental ignition. Which of the following chemical transformations occurs when a safety match is struck?

Options:

  • A: White phosphorus on the match head converts to red phosphorus due to frictional heat.
  • B: Potassium chlorate on the striking surface decomposes to release oxygen, which directly oxidizes the starch binder.
  • C: Red phosphorus on the match head reacts with potassium chlorate on the striking surface to produce sulfur dioxide.
  • D: Frictional heat converts a small amount of red phosphorus on the striking surface into white phosphorus, which ignites and initiates the reaction of potassium chlorate on the match head.
