Answer / my donkey
(E) None of the above
Most of the body is composed of water (H20), each molecule
of which contains two hydrogen atoms and one oxygen atom.
Therefore, hydrogen is the most abundant (numerous) element
in the human body. However, since oxygen is much heavier
than hydrogen, it comprises a greater percentage of the
body's weight (about 65%) than does hydrogen (about 10%).
