Solution
The correct option is A phosphorus
-
Phosphorus is a non-metal that catches fire when exposed to air. It is a highly reactive metal and spontaneously reacts with oxygen to catch fire.
-
Other non-metals like sulfur, nitrogen, and hydrogen don’t react with air, at room temperature, so they don’t catch fire.
