$I V > I I > I I I > I$

A

I V > I > I I > I I I

B

I V > I I > I I I > I

C

I I > I > I V > I I I

D

I > I V > I I I > I I

Solution

Verified by Toppr

The order of basicity among the following compounds is $I V > I > I I > I I I$

In IV, the extent of delocalization is maximum. When a lone pair of electrons on one of the $N$ atom is donated to a suitable acid, still some delocalization is possible.

However, in case of I, when a lone pair of electrons on one of the $N$ atom is donated to a suitable acid, further delocalization is not possible.

So, option C is correct.
