The correct answer is option A, that is, a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom.
Carbohydrates are the main source of diet, they provide energy to the body, mainly via glucose, a basic sugar, which is a part of the starch and an ingredient in various staple foods.
The carbohydrates can be signified by the stoichiometric formula, that is, (CH2O)n. It can be also be stated that the ratio of the carbon to hydrogen to oxygen is 1: 2: 1 in the molecules of carbohydrates. Carbohydrates are further categorized into three sub-kinds, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the simple sugars, for example, glucose.
Arteries are blood carrying vessels which have thick, elastic, muscular walls, have no valves and in which blood flows under high pressure. The make up of arteries is unique to their function of transporting blood under high pressure.
All arteries carry oxygenated blood from the heart to all other parts of the body, with the exception of the pulmonary artery which carries de-oxygenated blood from the heart to the lungs. It is the only artery that transports blood which has not been oxygenated.

Explanation:
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.
I've learned that the circulatory system is responsible for transporting nutrients and blood throughout the entire body :D
