Answer:

The correct answer is B. The virus can infect the host.

Explanation:

  • As the host and the virus both remain in the agar plate, the virus is capable of infecting the host cells.
  • The host cell multiplies and grows by utilising the nutrient from the agar medium.
  • After the virus particles infect the host, they replicate inside the host and produce new progeny virions which get released out of the host cell by killing it.
  • The newly formed virions infect other host cells and the process continues.
  • The killing of the host cells by the viruses result in the generation of clear zones on the agar plate which is also known as the zone of exclusion.
  • In the zone of exclusion region, the host cells have been killed by the viruses.
