The metals, present below hydrogen in the electrochemical series, cannot liberate hydrogen from the dilute acids.
Among the given metals only Ag is present below hydrogen in electrochemical series, so it does not evolve hydrogen with dil HCl.
Ag−I−dilHCl ⟶ No reaction

Hydrogen gas is not liberated when the following metal is added to dil...
Explanation:
When a metal is added to dilute hydrochloric acid (HCl), hydrogen gas is usually liberated. However, there are some exceptions where hydrogen gas is not liberated. One such exception is the metal silver (Ag).
The reason for this is that silver is less reactive than hydrogen, and therefore it does not displace hydrogen from hydrochloric acid. This is because in a displacement reaction, a more reactive element will displace a less reactive element from a compound.
In the case of silver and hydrochloric acid, the reaction that takes place is:
Ag + HCl → no reaction
This means that no hydrogen gas is liberated, and the silver metal remains unchanged.
On the other hand, metals like magnesium (Mg), tin (Sn), and zinc (Zn) are more reactive than hydrogen, and will therefore displace hydrogen from hydrochloric acid, resulting in the liberation of hydrogen gas.
For example, the reaction between magnesium and hydrochloric acid is:
Mg + 2HCl → MgCl2 + H2
This reaction produces hydrogen gas, which is liberated as bubbles.
Therefore, option C, silver (Ag), is the correct answer as hydrogen gas is not liberated when silver is added to dilute hydrochloric acid.
