If C is a liar then what he said about B is false.So, B is a truth teller.Now B's statement is based on A's statement which is true,as per which there is one truth teller and two liar.Now , B is already a truth teller.so, A and C must be lying.
But A is a truth teller( contradiction). So, then A and C must be telling truth and B is lying.
