Thus, the option is incorrect.

Carbohydrates include optically active substances made up of polyhydroxy aldehydes and ketones. These are sweet and are used in a household daily. It is divided into monosaccharides, disaccharides, and polysaccharides (like starch) based on its hydrolysis nature.

Thus, the option is correct.
