Viruses
B
Bacteria
C
Both viruses and bacteria
D
None of the above
Explanation: 

Detailed explanation-1: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles.

Detailed explanation-2: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-3: -Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do.

Detailed explanation-4: -All living things, including plants, animals, and microbes like bacteria and archaea, are susceptible to virus infection. There is no nucleus in a virus. Many typical cell components, like the mitochondria, nuclei, and even the ribosome, are absent in viruses. Even some of these viruses are cytoplasm-free.

Detailed explanation-5: -A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.
