What is a carbohydrate?
A
A biological polymer that stores and transmits genetic information
B
a group of organic molecules that includes sugars, starches, and glucose
C
An oil used for your car
D
hydrocarbon that contains only single bonds
Explanation: 

Detailed explanation-1: -A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are calle d monosaccharides.

Detailed explanation-2: -Carbohydrates are an important group of biological molecules that includes sugars and starches. Photosynthesis is the process by which plants use energy from sunlight to synthesize carbohydrates.

Detailed explanation-3: -In short-Monomer is a general term, while monosaccharide is a specific term for the monomer that makes up a carbohydrate. A monosaccharide is a single sugar molecule. This includes glucose, fructose, and galactose. Disaccharides are double sugars, such as sucrose (table sugar).

Detailed explanation-4: -Carbohydrate is a group of organic compounds occurring in living tissues and foods in the form of starch, cellulose, and sugars. The ratio of oxygen and hydrogen in carbohydrates is the same as in water i.e. 2:1. It typically breaks down in the animal body to release energy.

Detailed explanation-5: -Carbohydrates are organic molecules in which carbon (C) bonds with hydrogen and oxygen (H2O) in different ratios depending on the specific carbohydrate. Plants harvest energy from the sun and manufacture carbohydrates during photosynthesis.
