A chemical has been found to harm the same components in both prokaryotic and eukaryotic cells. Which components are those?

Prokaryotic and eukaryotic cells both contain DNA, a cell membrane, cytoplasm, and ribosomes. Membrane-bound organelles and a nucleus are not found in prokaryotic cells, so choices B, C, and D include components that cannot be shared by both cell types. The correct choice is A: DNA, cell membrane, cytoplasm, and ribosomes.
