Solution

The correct option is A $N a + H C l \to$
Reactive metals react with acids to release hydrogen gas. Sodium reacts with the hydrochloric acid and gives $NaCl$ and hydrogen gas with a lot of heat and then may even result in an explosion if concentration of sodium added is large enough.

$N a + H C l \to N a C l + H_{2}$

Other options given are bases. Hence, no release of hydrogen gas.
