Which of the following is a source of both monosaccharides and disaccharides?

Honey is indeed a source of both monosaccharides and disaccharides. It primarily contains fructose and glucose, which are monosaccharides, as well as sucrose, which is a disaccharide. The combination of these simple sugars makes honey a unique natural sweetener that provides quick energy due to the rapid absorption of monosaccharides.

Monosaccharides are the simplest form of carbohydrates and include sugars like glucose and fructose, while disaccharides consist of two monosaccharide molecules linked together, such as sucrose (glucose + fructose) and lactose (glucose + galactose). Honey's composition allows it to deliver both types of sugars.

In contrast, the other options either primarily contain other types of carbohydrates or do not contain significant amounts of sugars. Vegetables are generally low in sugars and primarily provide fiber and other nutrients. Brown rice is mainly a source of starch, which is a complex carbohydrate, and does not offer significant amounts of sugars. Fish, as a protein-rich food, contains minimal carbohydrates and therefore does not contribute to the intake of either monosaccharides or disaccharides.
