Which of the following statements are correct?

Options

A. `(I)` and `(II)` are aromatic and have equal basic strength.
B. `(I)` is aromatic, `(II)` is anti-aromatic , but `(II)` is a stronger base than `(I)`.
C. The basically order of above compounds is `(IV) gt (III) gt (II) gt (I)`
D. The conjugate acid of `(IV)` is more stabilised than the conjugate acid of `(II)`.

Answer

`(c,d)`

Explanation

In `(IV), the lone piar `oveline(e)'s` of two `N` makes it more basic and does not delocalise in the benzene ring.
In `(III)`, no delocalisationof `overset(..)(N)H_(2) . L.P` of `overset(e)'s`.
In `(II)` no delocalisation of `LP` of overline(e)` on `N`.
In `(I)` delocasation of `LP` of `overline(e)'s` on `N`, via resonance. Hence the order of basic character is: `(IV) gt (III) gt (II) gt (I)`.
