Aromatic compounds are cyclic, planar and must obey Huckel’s rule i.e. molecule must have $4 n + 2$ pi-electrons where n is an integer (i.e. $n = 0, 1, 2, 3, 4 \dots$ etc.). The compound B follws the Huckel's rule. The acid-base reactions fast reactions. Compound $(A)$ , also called squaric acid is a strong acid. So, above reaction proceeds very fast. All $C - C$ bond lengths in $(B)$ are same due to resonance. $(A)$ shows tautomerism. A
