I don't understand your explanation to question 43 in exam 1H.
43. C is correct. D is nonsense, since it has ten electrons on an oxygen, a
second period
element. A, B, and C are resonance structures of each other: choice C is
best, since
the negative formal charge is on the oxygens.

If D is incorrect, then C should also be incorrect because it has 10
electrons on 2 oxygens. I think your answer to this question is incorrect,
if not could you explain how is answer C correct.
