Solution

The correct option is B
Magnesium

Nitric acid does not liberate Hydrogen unlike other acids as it is a very strong oxidising agent. Any hydrogen initially produced by the action of a metal on nitric acid is at once oxidised by more of the acid to water and the reduction products of the acid like NO, NO₂ are formed

The acid is so dilute that its usual oxidising action is weakened and some hydrogen escapes oxidation
