"To be correct about something" using tener razón
If I want to say that someone is correct about something, do I use acera de, or sobre de or something else?
"You were correct about that question."

You could use acerca de, sobre, en que, en cuanto a, etc, but most of the time after hearing something we believe is correct we simply say Tienes razón.
I would use tener razón, and conjugate it based on whoever is right.
