- ABacteria contain cytoplasm but viruses do not
- BBacteria contain mitochondria but viruses do not
- CViruses contain mitochondria but bacteria do not
- DViruses have a cell membrane but bacteria do not
Explanation
Bacteria are prokaryotic cells possessing cytoplasm, ribosomes and a cell membrane, but they lack membrane-bound organelles such as mitochondria. Viruses are acellular - they consist only of genetic material inside a protein coat, with no cytoplasm, no cell membrane and no organelles of their own. Hence only statement A is correct.
