I believe its C. Atomic numbers represent the number of protons, thus, it can be concluded that an oxygen atom does indeed have more protons than a hydrogen atom :)
c. an oxygen atom has more protons than a hydrogen atom.
Explanation:
The atomic number corresponds to the amount of protons in the nucleus of the atom of a given chemical element. For example, the atomic number of hydrogen is 1, which means that it has only 1 proton in its atomic nucleus, while oxygen has atomic number 8, which means that it has 8 protons. From this we can conclude that an oxygen atom has more protons than a hydrogen atom.
