Viruses are considered as:

B. to have a nucleic acid core made of either DNA or RNA.

Viruses are not classified as living organisms because they cannot carry out metabolic processes on their own, nor can they reproduce independently without a host cell (which rules out options A and C). Additionally, they possess a protective protein coat (capsid), which contradicts option D. Therefore, the correct statement about viruses is that they have a nucleic acid core made of either DNA or RNA.
