Answer:
Hi, the statements given in the question (a and b) are combination of right and wrong answers. But i will split the statement a and b into necessary fragments.
Carbohydrates are quick source of energy relatively. That is the only correct statement in the question.
Explanation:
Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygen with the general formula (Cx H2y Oy) or Cx (H2O)y. They can be classified into simple sugar or complex sugar.
Simple sugars can be further divided into Monosaccharides (e.g glucose, fructose and galactose) and Disaccharides (e.g sucrose and maltose).
Complex sugar can be referred to as Polysaccharides (e.g cellulose and starch)
The statement above that says carbohydrate contains carbon, hydrogen and nitrogen polymers is not correct.
Carbohydrates are not mostly monosaccharides. They also contain Disaccharides and Polysaccharides.
They are not the only source of fuel.
