A Correct answer
Explanation

The head of a safety match contains an oxidizing agent, typically potassium chlorate (KClO3), which provides oxygen to sustain combustion when the match is struck. Phosphorus pentoxide (P2O5) is not used on match heads. Potassium chloride (KCl) is different from potassium chlorate.
