A compound is antiaromatic if it follows the Hückel's rule but has an odd number of π electrons. Compound III has 9 π electrons (3 from each double bond), which is an odd number and hence antiaromatic. The other compounds have either an even number of π electrons or do not follow Hückel's rule, and hence are not antiaromatic.
