D Correct answer
Explanation

Antimony sulphide (Sb2S3) is the combustible material at the tip of a safety match. When the match is struck against the striker surface (containing red phosphorus), friction generates heat that ignites the antimony sulphide, which then ignites the match stick. Sulphur is also present but antimony sulphide is the primary combustible.
