The human body is 98% water, and the remainder of the body is composed of minerals and hydrocarbons. Since water and hydrocarbon molecules both contain multiple hydrogen atoms, hydrogen is probably the correct answer.

Either hydrogen or carbon. Probably hydrogen. The body uses an awful lot of oxygen, and can't live long without it. Sorry I wasn't helping much.
