B. nuclease (destroys DNA and RNA)
Explanation:
Viruses are the particles that contain a protein coat called the capsid. Inside the capsid, viruses have their genetic material. Viruses may have single-stranded or double-stranded DNA molecules or single-stranded or double-stranded RNA molecules as their genetic material. Therefore, to destroy viruses, one must target their genetic material. Nucleases are enzymes that digest nucleic acids (DNA and RNA). The use of nucleases would destroy the genetic material of viruses and would be most effective to control them.
