B
Hydrogen
C
Oxygen
D
Nitrogen
E
Phosphorus
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: -Carbohydrates are a group of organic compounds containing a ratio of one carbon atom to two hydrogen atoms to one oxygen atom.

Detailed explanation-3: -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-4: -This view represents these molecules simply as “hydrated” carbon atom chains in which water molecules attach to each carbon atom, leading to the term “carbohydrates.” Although all carbohydrates contain carbon, hydrogen, and oxygen, there are some that also contain nitrogen, phosphorus, and/or sulfur.

Detailed explanation-5: -Carbohydrate is made up of carbon, hydrogen and oxygen. Its chief function is to provide energy for physiological activities. Starch, sugar, glucose and cellulose are different forms of carbohydrate.
