Question

all living things are made of... multiple cells. one or more cells. prokaryotic cells. eukaryotic cells.

Explanation:

The cell theory states that all living things are composed of one or more cells. Some organisms are unicellular (made of one cell), like bacteria (prokaryotic cells), and some are multicellular (made of many cells), like humans (eukaryotic cells). The option "multiple cells" is incorrect because there are unicellular organisms. "Prokaryotic cells" and "eukaryotic cells" are too specific as not all living things are made only of prokaryotic or only of eukaryotic cells.

Answer:

one or more cells.
