Verified step by step guidance

Understand the structure of lactose: Lactose is a disaccharide composed of one molecule of glucose and one molecule of galactose.

Identify the sugar subunits of each option: Glucose is a monosaccharide, ribose is a monosaccharide, maltose is a disaccharide composed of two glucose units, and cellobiose is a disaccharide composed of two glucose units.

Recognize that galactose is a monosaccharide that pairs with glucose to form lactose.

Compare the sugar subunits of each option to determine which contains galactose: Only lactose contains galactose as one of its sugar subunits.

Conclude that lactose is the correct answer because it is the only option that includes galactose as a component.
