What hazard is produced when alkali metals react with water?

Explanation:
When alkali metals meet water, they form metal hydroxide and release hydrogen gas. The hazard here is the hydrogen gas, because it’s highly flammable and can ignite or explode if it builds up and encounters a spark or heat from the reaction. The other gases listed aren’t produced by this reaction (oxygen, chlorine, and nitrogen aren’t formed in this situation), so they don’t present this particular hazard.
