Q. The correct stability order of the following resonance structures is $\underset{(I)}{H_2C = \overset{+}{N} = \overset{-}{N}}\,\,\,\,\underset{(II)}{H_2\overset{+}{C} -N = \overset{-}{N}}\,\, \,\,\underset{(III)}{H_2\overset{-}{C} -\overset{+}{N} = N}\,\, \,\,\underset{(IV)}{H_2\overset{-}{C} - N = \overset{+}{N}}$
