When drawing a Haworth perspective formula from a Fisher projection, which statement is TRUE regarding anomers?
A) It is $\alpha$ if the hydroxyl group on the anomeric carbon is up.
B) It is $\alpha$ if the hydroxyl group on the anomeric carbon is down
C) It is $\alpha$ if the hydroxyl group on the anomeric carbon on the same side of the ring as the C6
D) It is $\alpha$ if the hydroxyl group on the anomeric carbon on the opposite side of the ring as the C6
E) None of the answers is correct.

In the Haworth projection, an anomer is α if the hydroxyl group on the anomeric carbon (carbon-1 for glucose) is on the opposite side of the ring from the CH2OH group attached to carbon-6. This means the hydroxyl group and the CH2OH group are trans to each other.
