Which of the following does not contain enzymes?

Viruses do not contain enzymes. Unlike algae, lichen, and bacteria, which are living organisms with cellular structures and metabolic processes that involve enzymes, viruses are much simpler entities. They consist mainly of genetic material (either DNA or RNA) surrounded by a protein coat. Viruses lack the cellular machinery necessary to produce enzymes or carry out metabolic activities on their own. Instead, they rely entirely on the host cell’s machinery to replicate and produce the proteins and enzymes they need for their life cycle. This lack of enzymes is one of the reasons viruses are considered to be on the boundary between living and non-living.
