Quizplus · Accepted Answer

The anomeric carbon is the carbon involved in the hemiacetal or hemiketal formation in a cyclic sugar. In this case, the carbon connected to both the oxygen and the CH2OH group (the alpha side) is the anomeric carbon, which is carbon 2. Therefore, the correct answer is B.
