Among a sample of ancient Chinese coins from the Tang dynasty, each face of any coin displays one of four images: an emperor’s face, a queen’s face, a Chinese word “treasure”, or a Chinese word “money”. By examining the coins available, a coin collector finds that none of them have faces on both sides and that all coins in the sample with an emperor’s face on one side have a Chinese word “treasure” on the other.
If the statements above are true, which one of the following must also be true?
(A) All coins with a queen’s face on one side have a Chinese word “money” on the other.
(B) All coins with a Chinese word “treasure” on one side have an emperor’s face on the other.
(C) None of the coins with a Chinese word “money” on one side have a queen’s face on the other.
(D) None of the coins with a Chinese word “treasure” "money"on one side have an emperor’s face on the other.
(E) None of those with a queen’s head face on one side have a Chinese word “treasure” on the other.
