Solution

The correct option is A

Sodium (Na)


Highly reactive metals such as potassium and sodium react violently with cold water. The reaction is so violent and exothermic that the evolved hydrogen immediately catches fire.

Metals react with water and produce a metal oxide and hydrogen gas.

2Na(s) + H2O(l) Na2O(s) + H2(g)
