The term carbohydrate is derived from the French word known as ‘Hydrate de carbone’ which means hydrate of carbon so we can say that carbohydrates comprises carbon, hydrogen and oxygen. The general formula of carbohydrates can be represented as $C_n{(H_{2}O)}_n$. These can also be known by some other names like starch, simple sugars etc.
The carbohydrates can be further classified into simple and complex carbohydrates on the basis of their chemical structure and degree of polymerization.

Hence from the above discussion we can say that option D is the correct answer.
