In honey, the sugar that predominates is fructose. Honey is primarily made up of two types of sugar: fructose and glucose. These sugars are naturally occurring and are derived from the nectar of flowers. While both fructose and glucose are present in honey, fructose is the sugar that is found in higher concentrations.

Sucrose, which is an equal combination of fructose and glucose, is not the predominant sugar in honey. Sucrose is found in much lower amounts in honey.

Galactose and maltose are not the predominant sugars in honey either. Galactose is not typically found in significant amounts in honey, and maltose, which is a disaccharide made up of two glucose molecules, is also not present in high quantities.

Therefore, option 2 - fructose is the correct answer as it is the sugar that predominates in honey.
