(iv) galactose
(v) fructose

Explanation

To classify the given sugars into monosaccharides and disaccharides, we first need to understand the definitions of these terms:

1. **Monosaccharides**: These are the simplest form of carbohydrates and cannot be hydrolyzed into simpler sugars. They consist of a single sugar unit.

2. **Disaccharides**: These are carbohydrates composed of two monosaccharide units linked together. They can be hydrolyzed into their constituent monosaccharides.

Now, let's classify the given sugars:
