carbanion stability$\propto -M\propto -I\propto \frac{1}{+I/+HC}\propto \frac{1}{+M}$




In (II), stability is increased as there is an electron withdrawing group, hence it stabilizes, but in (I) and (IV), it increases the electron density whereas in (III), there is no functional group attached for electron donation or withdrawal.
