Which of the following is applied on the top of the matchsticks?
- ARed phosphorus
- BWhite phosphorus
- CPotassium sulphate
- DNo option is correct
Solution & Step-by-step Explanation
The head of a safety matchstick typically contains an oxidizing agent such as potassium chlorate, along with sulfur, fillers, and glass powder. Red phosphorus is applied to the striking surface of the matchbox, not the tip of the matchstick itself. Therefore, "No option is correct" is the right choice among the given ones.
