For the ion shown, select all the atoms that carry negative charge in at least one resonance contributor.

AThe oxygen atom
BThe two ortho carbons
CThe two meta carbons
DThe para carbon

Answer: A, B, D

The ion shown is the phenoxide ion. The charge can move from oxygen to the ortho and para carbons through the ring, but never to the meta carbons. So oxygen, ortho and para carbons are correct.
