The correct answer is C. α-D-glucose and β-D-glucose.

Anomeric pairs refer to two stereoisomers of a cyclic saccharide that differ only in their configuration at the hemiacetal or hemiketal carbon, also called the anomeric carbon. In the case of glucose, this is carbon 1.

α-D-glucose and β-D-glucose are anomers. They have the same molecular formula and sequence of bonded atoms, but a different orientation of the hydroxyl group (-OH) around the anomeric carbon. In α-D-glucose, the -OH group is on the opposite side (trans) of the ring as the CH2OH group, while in β-D-glucose, the -OH group is on the same side (cis) of the ring as the CH2OH group.

The other pairs listed are not anomeric pairs. D-glucose and L-glucose (A) are enantiomers, mirror images of each other. D-glucose and D-fructose (B) are different types of sugars altogether, an aldose and a ketose, respectively. α-D-glucose and β-L-glucose (D) differ in the configuration of multiple carbons, not just the anomeric carbon. D-glucose and L-fructose (E) are different types of sugars and also enantiomers.
