What is the enantiomer of D-glucose?

✅Explanation:
An enantiomer is a mirror image of a molecule that is non-superimposable on the original molecule, much like left and right hands. For sugars, the enantiomer of a D-sugar (like D-glucose) is its corresponding L-form (like L-glucose).

📌Other Options Explanation:

•  (a) D-Fructose:
-D-Fructose is a structural isomer with a different arrangement of atoms (a ketohexose vs. an aldohexose).

•  (b) L-Fructose:
-L-Fructose is the mirror image of D-Fructose.

(d) D-Galactose:
-D-Galactose is an epimer of D-Glucose (differing at one chiral carbon)
