Solution

When zinc reacts with dilute sulphuric acid then it gives zinc sulphate and hydrogen gas will evolve.
$Zn (s) + H_{2} {SO}_{4} (aq) \to {ZnSO}_{4} (aq) + H_{2} (g)$
So, from the following given setups in setup 4 hydrogen gas will evolve easily as there is proper space for the gas to evolve.

Hence the correct option is 4.

When zinc reacts with dilute sulphuric acid then it gives zinc sulphate and hydrogen gas will evolve. Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g) So, from the following given setups in setup 4 hydrogen gas will evolve easily as there is proper space for the gas to evolve. Hence the correct option is 4.
