There are four doors X, Y, Z, W leading out of the Middle Sanctum. At least one of them leads to the Inner Sanctum. If you enter a wrong door, you will be devoured by a fierce dragon.
Well, there were eight priests A, B, C, D, E, F, G, H, each of whom is either a knight or a knave. They made the following statements to the philosopher:
A: X is a good door.
B: At least one of the doors Y, Z is good.
C: A and B are both knights.
D: X and Y are both good doors.
E: X and Z are both good doors.
F: Either D or E is a knight.
G: If C is a knight, so is F.
H: If G and I are both knights, so is A. (H is referring to himself when he says “I.”)
Which door should the philosopher choose?

also, request for clarification.
G: If C is a knight, so is F
H: If G and I are both knights, so is A.
Do these mean "if and only if"

I suggest, we should post a puzzle only if we are ready to own it and have a definite answer. This will save the members' time.
my friend gave me this puzzle and this is all there is. im still new to these logic puzzles so i thought maybe someone else could figure it out. but i also thought there was info missing and im glad im not the only one. thanks for the attempts
