Solution

The false statement is (b) D-glucose and D-galactose are epimers.

Epimers are diastereomers that differ in configuration at only one stereogenic center. D-glucose and D-galactose are not epimers. They differ in configuration at the C4 position. The correct epimer of D-glucose would be D-mannose, which differs at the C2 position.
