• B. They have prokaryotic nucleus.
• C. They have single chromosome.
• D. They have both DNA and RNA.

Answer 1

The correct option is A They have either RNA or DNA enclosed in a protein coat.

Viruses have either RNA or DNA as their genetic material. The entire infectious virus particle, consists of the nucleic acid and an outer shell of protein called caspid.
Viruses are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living cells). Chromosomes are present only in eukaryotic organisms.
