I answered three curvatures; (one curvature for the cervical vertebra, one curvature for the thoracic and one for the lumbar)....but my answer was wrong!

I'm thinking it might be two. Is there a distinct curvature in the cervical vertebra?

Now I think it might actually be four. Should I have added one more curvature at the sacrum?

I'm not sure why you got the question wrong. There are indeed three distinct curvatures in the normal spinal column. And they are the ones you named.
Perhaps they intended you to include the sacral spine, which would make the answer four curvatures.
I found two sources with different answers, one says three: cervical, thoracic and lumbar. The other says four: cervical, thoracic, lumbar and sacral.
