None of the above

Explanation:
Detailed explanation-1: -Carbohydrates usually have a ratio of two hydrogen molecules for one oxygen molecule, just like water along with the same number of oxygen atoms and carbon atoms.
Detailed explanation-2: -Carbohydrates are made of carbon (C), hydrogen (H), and oxygen (O), or CHO, in an approximate ratio of 1:2:1.
Detailed explanation-3: -Let’s start with a carbohydrate definition. Carbohydrates, or carbs as they are known colloquially, are energy storing organic compound molecules made up of carbon, hydrogen, and oxygen in a 1:2:1 ratio. Because of this, all carbohydrates follow the empirical formula of C n H 2 O C n H 2 O CnH2O.
