Read Solution (Total 5)

Door C leads to freedom. Statement on door A is wrong.

Solution:

Statement C follows B. So either B and C are true or false.

But only one statement is wrong. So both are true.

Now statement A is false and it does not leads to freedom.

So door C leads to freedom. Door B leads to Ghost house and C confirms it.
