The living things show a characteristic feature which is that all living organism whether unicellular or multi-cellular, whether prokaryote or eukaryote are made up of cells.
Since, in the given question, a bacterium represents a prokaryotic organism, an amoeba represents a eukaryote and the carrot represents a multicellular organism, therefore, they all are made of the structural and functional unit called cells.
Thus, they all are living and thus are made of cells is the correct answer.
