Solution

The correct option is D Hydrogen
Metals which are more reactive than hydrogen displace it on reaction with a dilute acid. They form their respective salts and liberate hydrogen gas.
$M e t a l + d i l . A c i d \to S a l t + H y d r o g e n$

Metal hydrogencarbonate with dilute acids undergoes double displacement reaction and forms products such as $H_{2} C O_{3}$ and salt of respective metal.
The rapid decomposition of carbonic acid releases $C O_{2}$ and $H_{2} O$
$M e t a l h y d r o g e n c a r b o n a t e + d i l . A c i d \to S a l t + C a r b o n d i o x i d e + W a t e r$
