Which has more entropy: a shuffled deck of playing cards or an unshuffled deck of the same make and brand?

A) These cards have the same entropy because they are made of the same material, have the same mass, and are at the same temperature.
B) The shuffled deck has more entropy since it has a greater measure of disorder.
C) The unshuffled deck has more entropy because it comes packaged with a totally random order of appearance. Shuffling the deck ultimately adds order and reduces entropy.
D) The difference in entropy in the two decks could only be determined after examining both stacks of cards side by side once the unshuffled deck had been shuffled.
