When a Monosaccharide Forms a Cyclic Hemiacetal,the Carbon Atom That

When a monosaccharide forms a cyclic hemiacetal,the carbon atom that contained the carbonyl group is identified as the ________ carbon atom because

A) D; the carbonyl group is drawn to the right.
B) L; the carbonyl group is drawn to the left.
C) anomeric; its substituents can assume an α or a β position.
D) acetal; it forms bonds to an -OR and an -OR'.
E) enantiomeric; depending on its position,the resulting ring can have a mirror image.
