Solution

The correct option is D Fourth carbon atom
Single hexoses, glucose, and galactose require no digestion and can be absorbed directly into the bloodstream. Three common sugars-glucose, galactose, and fructose share the same molecular formula: C6H12O6. Because of their six carbon atoms, each is a hexose.
So, the correct option is 'Fourth carbon atom'.
