Solution

The correct option is D Viruses
  • Measles, mumps, rubella, and varicella (commonly known as chickenpox), influenza are the chronic diseases of a virus.
  • These can be prevented from spreading by using vaccines. This vaccine works by prior exposure of a small dose of the virus or a protein from the virus, which activates the immune response.
Therefore, the correct answer is option B.
