Ok, so I am studying for my MCAT and on a practice EK test I have this question. They told me I was wrong, but i am quite certain I am correct. Can someone help?

QUESTION:

The correct hybridizations of the C and N in Uric Acid are?

MY ANSWER:

I put, C as sp2 because it only has three sigma bonds. Additionally, I put the Nitrogen as sp2 because it has only three sigma bonds, and only three because its lone pair is delocalized and participates in resonance?

THEIR ANSWER:

They said this was wrong and that you have to include the lone pair in the hybridization of N, so that the answer was C as sp2 and N as sp3?

Am I correct?
