Viruses recognize copper ions as an essential nutrient and absorb them into their cells. B. The absorbed copper ions create holes in the cell membrane, depriving the virus of necessary nutrients and water. C. Ultimately, the virus's respiration and activity are significantly inhibited, its DNA is damaged, and it dies.
