C
Carbon, oxygen and glucose
D
Carbon, hydrogen and oxygen
Explanation: 

Detailed explanation-1: -Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.

Detailed explanation-2: -The common attributes of carbohydrates are that they contain only the elements carbon, hydrogen and oxygen, and that their combustion will yield carbon dioxide plus one or more molecules of Water.

Detailed explanation-3: -Sugars. Carbohydrates or sugars are a class of organic molecules containing carbon, oxygen and hydrogen. They are found as monomers (single molecules), as dimers (two linked molecules) and as long-chain polymers.

Detailed explanation-4: -Carbohydrates are a group of organic compounds containing a ratio of one carbon atom to two hydrogen atoms to one oxygen atom. Basically, they are hydrated carbons. The word “carbo” means carbon and “hydrate” means water.

Detailed explanation-5: -Carbohydrates are molecules made of carbon, hydrogen and oxygen and may not contain other elements such as sulfur or nitrogen.
