Select the correct statement with respect to diseases and immunisation:

  1. A
    Certain protozoans have been used to mass produce hepatitis vaccine.
  2. B
    Injection of snake antivenom against snake bite is an example of active immunisation.
  3. C
    If due to some reason -and -lymphocytes are damaged, the body will not produce antibodies against a pathogen.
  4. D
    Injection of dead/inactivated pathogens causes passive immunity.

Solution & Step-by-step Explanation

-lymphocytes (plasma cells) are responsible for producing antibodies. -helper cells stimulate -cells to produce these antibodies. If both are damaged, the antibody-mediated immune response is lost. Snake antivenom is passive immunity, and dead pathogens induce active immunity.
