c. a prokaryotic unicellular organism
d. nucleic acids surrounded by a protein coat

D. nucleic acids surrounded by a protein coat

Explanation:

A virus is a small infectious organism that replicate inside the body of the host  cell to produce progeny viruses. It can infect all life forms such as plants, animals, microorganisms and others.

The structure of the virus includes a protein coat that is called as a capsid. Inside the capsid the genetic material in the form of nucleic acid (RNA or DNA) is present which is injected into the host cell to facilitate the replication process.
