(C) Let us analyze each option:$A$: The isopropyl carbanion $(CH_3-CH^--CH_3)$ is less stable than the ethyl carbanion $(CH_3-CH_2^-)$ due to the greater $+I$ effect of the two methyl groups.$B$: Cyclobutadiene is anti-aromatic ($4\pi$ electrons),while $1,3-$butadiene is non-aromatic. Thus,$1$,$3$-butadiene is more stable.$C$: The carbocation $(MeO)_2C^+$ is highly stabilized by the resonance effect $(+M)$ of the two methoxy groups,making it significantly more stable than the tert-butyl carbocation $(t-Bu^+)$,which is only stabilized by hyperconjugation and the $+I$ effect.$D$: The tris(trifluoromethyl)methyl carbanion is extremely stable due to the strong $-I$ effect of the three $CF_3$ groups,making it much more stable than the isopropyl carbanion.
