and yeah i confirmed that D is planar tropylium ion it is aromatic no way 4 methyl groups on A overwhelm the aromaticity of D? A seems anti-aromatic too, unless it twists out of plane or something

bro, when H+ is removed, anion is formed not cation so A has 6 pi electrons after H+ removal while D has 8pi electrons
