A) enantiomers
B) meso compounds
C) C2 epimers
D) C4 epimers
E) D-glucose and D-galactose

Ruff Degradation

A chemical process used to shorten the carbon chain of sugars by one carbon atom, involving the oxidation of an aldose sugar to the corresponding aldonic acid, followed by its decarboxylation.

D-aldopentoses

A type of sugar containing five carbon atoms, including an aldehyde group at the first carbon.

D-aldotetrose

A simple sugar (tetrose) in the D-configuration with an aldehyde group, part of the carbohydrate family.

Final Answer :
C
Explanation :
C2 epimers of D-aldopentoses can give the same D-aldotetrose upon Ruff degradation because the process involves the shortening of the carbon chain by one carbon atom from the aldehyde end, and the configuration at C2 determines the stereochemistry of the resulting aldotetrose.
