JEE Main 28 June 2022, Shift 1, Chemistry Q72

Question 72 of 90 in this shift, Chemistry question 12 of 30, Section A.

Which of the following structures are aromatic in nature ?

The figure, in words

Four ring structures labelled A to D drawn side by side. A: five-membered ring with two C=C double bonds drawn, the bottom ring atom carries a circled minus charge. B: seven-membered ring with three C=C double bonds drawn, the bottom ring atom carries a circled plus charge. C: two fused six-membered rings (shared bond) with four C=C double bonds drawn, two in each ring and none on the shared bond (the two shared carbons have no double bond). D: seven-membered ring with three C=C double bonds drawn, the bottom ring atom carries a circled minus charge.
