Correct Answer

D

Explanation

One of the key elements used in the production of matches is phosphorus. Phosphorus compounds, particularly phosphorus sesquisulfide (P4S3), are commonly used in the striking surface of matchboxes. When the match head is struck against this surface, friction generates heat, causing the phosphorus to react with potassium chlorate or another oxidizing agent present in the match head. This chemical reaction produces the necessary heat and ignition for the match to light. It's important to note that the use of white phosphorus in matches has declined due to safety and environmental concerns, and safer alternatives are often employed in modern match production.
