Which of the following does not have any enzyme in its cells?

Correct answer: (e) None of the above / More than one of the above

Explanation

Enzymes are biological catalysts present in all living cells; lichens, bacteria and algae all contain enzymes.

A virus has no cells of its own, and some viruses carry enzymes such as reverse transcriptase (retroviruses), so it does not fit the question cleanly either.

The Commission’s key is therefore option (e).
