Solution

The correct option is A $(I I I) > (I V) > (I I) > (I)$
In the given amines $I I I$ is strongest base as the lone pairs of nitrogens with one double bond are electron negative and in conjugation, therefore, increases the electron density. In $I V$ the presence of $+ I$ effect of alkyl group increases its basicity. Cyclohexylamine is weak base as there is no additional effects but in the compound, $I$ presence of two nitro groups $(- M e f f e c t)$ makes the amine electron-deficient and least basic.
The order of basic strength is $I I I > I V > I I > I$
