(D) compound is antiaromatic if it is cyclic,planar,fully conjugated,and contains $4n \pi$ electrons (where $n = 1, 2, ...$).$(I)$ Furan: $6 \pi$ electrons (aromatic).$(II)$ Cycloheptatriene: Not fully conjugated (non-aromatic).$(III)$ Cyclooctatetraene: Non-planar tub-shaped (non-aromatic).$(IV)$ Cyclopentadienyl anion: $6 \pi$ electrons (aromatic).$(V)$ Cyclopentadienyl cation: $4 \pi$ electrons,planar,fully conjugated (antiaromatic).$(VI)$ Cyclobutadiene: $4 \pi$ electrons,planar,fully conjugated (antiaromatic).Therefore,compounds $(V)$ and $(VI)$ are antiaromatic.
