Solution

The correct option is A $I > I I > I I I$
the strength of basic nature of compounds depends on the ability to easily donate the lone pair of electrons.
IN $(i)$ lone pair is easily approachable so it has more basicity . in $(i i)$ the lone pair is in different plane. while in $(i i i)$ the lone pair is in conjugation . hence order of basicity is $I > I I > I I I$
