Solution

The correct option is A $(I) > (I V) > (I I I) > (I I)$
Therefore, the order of acidic character,
$A r o m a t i c > N o n - a r o m a t i c > A n t i - a r o m a t i c$
But anti-aromacity of $(I I I)$ is more than $(I I)$ since $(I I I)$ is more resonance stabilised than $(I I)$
Therefore, the order of decreasing acidic character or $K_{a}$ value is $(I) > (I V) > (I I I) > (I I)$
