There are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of mass.
Why is this statement true?
Hydrogen is a gas, but oxygen is a solid.
Hydrogen atoms have a lower mass than oxygen atoms.
Hydrogen atoms make up more of water's mass than oxygen atoms.
Hydrogen is present as single atoms and oxygen is bonded in compounds.

The correct explanation is: Hydrogen atoms make up more of water's mass than oxygen atoms. Water (H2O) is a common molecule in living organisms and it consists of two hydrogen atoms and one oxygen atom. Since water is a crucial component of living organisms, the abundance of hydrogen atoms in water contributes to the overall higher number of hydrogen atoms in living organisms compared to any other atom.
