Fructose is considered the sweetest of all the common sugars. It is a monosaccharide that is sweeter than glucose, sucrose, and lactose. Fructose is found in honey, fruits, and root vegetables, and is often used as a sweetener in foods and beverages.
- Glucose is sweet but not as sweet as fructose.
- Lactose is a disaccharide found in milk and has a less sweet taste than fructose.
- Sucrose (table sugar) is a disaccharide consisting of glucose and fructose but is not as sweet as fructose alone.
Thus, the correct answer is option (D) Fructose.
