Solution

The correct option is A hydrogen
Metals react with water to form metal oxides or metal hydroxide and hydrogen.
Some examples are shown:
$2 N a + 2 H_{2} O \to 2 N a O H + H_{2}$
$2 K + 2 H_{2} O \to 2 K O H + H_{2}$
$2 A l + 3 H_{2} O \to A l_{2} O_{3} + 3 H_{2}$
Thus, Option $A$ is correct.
