Carbon, Hydrogen, Nitrogen, and Oxygen are the four most common elements.
The human body is made up of only mostly carbon, oxygen, hydrogen, nitrogen, calcium, and phosphorus. The top four elements are oxygen, carbon, hydrogen and nitrogen, so that would be a. on your list.
All proteins contain carbon, hydrogen, oxygen and nitrogen. Most of them also contain sulfur, which is found in the standard amino acid residues cysteine and methionine (any given protein might not contain either of these, though it would be unusual).
The most abundant elements in the universe, in order from most to least abundant, are Hydrogen, Helium, Oxygen, Carbon, and Nitrogen. Therefore, the correct list would start with Hydrogen, followed by Helium (not listed), then Oxygen, Carbon, and finally Nitrogen. The first option you provided, "Hydrogen Oxygen Nitrogen Carbon," is almost correct but is missing Helium and has an incorrect order for Nitrogen and Carbon.
The four most common elements in living things are carbon, hydrogen, oxygen, and nitrogen. These elements are essential for building organic molecules like carbohydrates, lipids, proteins, and nucleic acids that make up living organisms.
