1 5

2 1

3 3

4 4

Explanation:

(a) is not planar
(b) Ring is planar but hydrogens are not
(c) Benzene is planar
(d) The expected hybridization of N in Pyrrole is $s p^{3}$ but the unavailability of the lone pair and partial double bond character with $N \equiv C$ bonds, makes this molecule planar.
(e) The expected hybridization of O in furan is $s p^{3}$ but one of the 2 lone pairs gets involved in resonance. Hence, the effective hybridization in $s p^{2}$ which means, furan is planar.
