Solution

The correct option is C X:- Sodium, Y:- Hydrogen
Metals on reaction with acids, produce metal salts and hydrogen gas except copper, gold etc.

When sodium reacts with dilute $HCl$ it forms sodium chloride and hydrogen gas. The reaction involved is:

$Sodium + Hydrochloric Acid \to Sodium chloride + Hydrogen gas$

Moreover, when it reacts with the cold water it will form sodium hydroxide and hydrogen gas. The hydrogen gas formed immediately catches fire because this reaction generates a lot of heat.

$Sodium + Water \to Sodium hydroxide + Hydrogen gas$

So, X is sodium and Y is hydrogen.
