Explanation:
Carbohydrates are one of macro molecules made up of carbon, hydrogen and oxygen. These are essential molecule as they provide nutrition and makes structural component in plants too.
The ration of carbon, hydrogen and oxygen is similar in almost every sugar or carbohydrate which is 1:2:1, one carbon molecule and one oxygen molecule per two molecule of hydrogen.
In choice A, and B have no oxygen molecule so they can not be carbohydrate, where as D have inappropriate ration in comparison to the carbohydrates.
Thus, the correct answer is :
A. C4H8C4 - NOT
B. C12H12C4 - NOT
C. CóH1206 - yes
D. C4H2020 - NOT
