Thank you Dr Krooks. I have a doubt regarding fifth que, when viewed sagitally both anterior and posterior teeth are mesially inclined. But otherwise the mandibular posterior teeth are distally inclined and linguallyinclined. Is it correct. Ple correct me if i am wrong.

well i have same doubt ...in decks it says that crown is distally and lingually inclined ..
but from what i know that all teeth are inclined mesially...
can someone explain this for both of us
thanks
If there was an option with Ant. teeth straight and Post. teeth Mesially inclined, I would have gone for it.
But in the given options, C seems to be correct.
