Among the given sets, which represents the resonating structures ?

A
$H - C \equiv \mathop N\limits^ + - \mathop O\limits_{ \bullet \bullet }^{ \bullet \bullet } \mathop :\limits^ - \,$ and $H - \mathop O\limits_{ \bullet \bullet }^{ \bullet \bullet } - C \equiv N:$
✓
$H - \mathop O\limits_{ \bullet \bullet }^ + = C = \mathop N\limits^{ \bullet \bullet } \mathop :\limits^ - $ and $H - \mathop O\limits_{ \bullet \bullet }^{ \bullet \bullet } - C \equiv N:$
C
$H - C \equiv \mathop N\limits^ + - \mathop O\limits_{ \bullet \bullet }^{ \bullet \bullet } \mathop :\limits^ - \,$ and $\begin{array}{*{20}{c}}
{:O:}\\
{||}\\
{H - C - \mathop N\limits_{}^{ \bullet \bullet } :\,}
\end{array}\,$
D
$H - \mathop O\limits_{ \bullet \bullet }^{ \bullet \bullet } - C \equiv N\mathop :\limits^ - $ and $H - \mathop N\limits^{ \bullet \bullet } = C + \mathop O\limits^{ \bullet \bullet } :$

Answer

Correct option: B.

$H - \mathop O\limits_{ \bullet \bullet }^ + = C = \mathop N\limits^{ \bullet \bullet } \mathop :\limits^ - $ and $H - \mathop O\limits_{ \bullet \bullet }^{ \bullet \bullet } - C \equiv N:$
