A

$\underset{‾}{\text{Explanation}}$: 

The above green area is the deadweight loss incurred due to the quota. When the quota is removed, overall economic welfare increases by that amount.

Choice B is wrong, as domestic consumers pay $P_{\mathrm{W}\mathrm{O}\mathrm{R}\mathrm{L}\mathrm{D}}$ after the quota is eliminated.

Choice C is wrong, as the domestic consumer surplus decreases by the blue area.

Choice D is wrong, as the value of net exports should decrease, as the country imports more now ($Q_1{Q}_5>Q_1{Q}_3$).
