see the question is for a carbanion. a carbanion has negative charge and is a reaction intermidiate. we know that NO2 shows very strong -R effect, i.e pulls the electrons towards itself through resonance, therefore the negative charge on carbanion gets reduced which increases the stability. -R effect is strongest in ortho position followed by para position, then meta, and finally the compound having no -R, so the order is I>III>II>IV . please feel free to ask if you have any more doubts and please approve if you like the answer :)
