Stability of resonating structure

Write the stability order of Resonating Structures:

In an aromatic ring, a functional group with lone pair of electron exerts +M effect, some fnuctional groups like, -NO,-NC-CH=CH_(2) etc., can function both as electron donating (+M) or electron withdrawing (-M) groups. More extended conjugation provide more stabilization. The most stable resonating structure is :
