Lactose is which sugar?

Explanation:
Lactose is sugar that is found in milk and dairy products; it is a disaccharide made of glucose and galactose, which is why it’s commonly called milk sugar. The other names point to different sugars: fruit sugar refers to fructose, which is abundant in fruits; table sugar is sucrose, a glucose–fructose disaccharide; and “plant sugar” isn’t a specific sugar, since plants contain glucose and sucrose among others. So lactose is specifically the sugar associated with milk.
