Solution
The correct option is D hydrogen
The chemical compounds which liberate H+ ions upon dissolution are known as acids.Therefore, upon reacting with metals which are more reactive than hydrogen, the metal replaces hydrogen, and the independent H atoms combine to form H2 gas.Hence, the evolved gas was hydrogen as all the given metals are more reactive than hydrogen.
