Solution

The correct option is A $s a l t + H_{2}$
When an acid reacts with metal, a salt and hydrogen gas are produced.
$M e t a l + A c i d \to S a l t + H_{2}$ .
The salt formation depends on the metal and acid that are reacting.
For example :- When Nitric acid $(H N O_{3})$ [an acid] reacts with Calcium $(C a)$ [a metal], then Calcium nitrate $C a (N O_{3})_{2}$ [a salt] is formed along with formation of hydrogen gas (since the hydrogen liberated by the acid combine to form $H_{2}$ ).
$2 H N O_{3} + C a \to C a (N O_{3})_{2} + H_{2}$
Hence, the correct answer is option (A).
