The answer is 'C' - All cells contain the same key elements - Carbon, Hydrogen, Oxygen, Nitrogen, Phosporus, and even Sulfur.
The uniqueness of cells that are animal, plant or single cell vs. multicellular comes from how these chemical elements are built into large bio-molecules that are specialised.
