Answer

The correct answer is C.

Explanation

An atom consists of a nucleus made up of protons and neutrons, surrounded by a cloud of electrons. The nucleus is indeed small when compared to the entire atom but contains the majority of the atom's mass due to the significant contribution of protons and neutrons. This relationship highlights how the nucleus, while tiny in size, is crucial in determining the mass of the atom.
