Answer»

Right choice is (d) IMMUNOGENIC but not infectious

Easy EXPLANATION: An immunogenic organism can EVOKE the immune response when entered inside a host. Immunosuppressive organism can suppress the host immune response and infectious organism can cause infection to the host. VLP or Virus like particles are the outer protein COVERING of the virus with no viral genetic material. Hence, they can evoke host immune response but cannot cause infection to the host.
