Correct answer: D). People do not have immunity to a new strain of the influenza virus.

The main cause is that the influenza virus constantly changes its DNA, this enables the virus to invade the immune system. It works as follows, if a  person is affected by the influenza virus then the body prepares antibodies against it.

But as the virus changes its genetic makeup constantly the older antibodies will not be able to recognize the new virus and the body get infected. That is the main reason for the outbreak of the influenza virus.

Hence, the correct answer would be option D.

If people do not have immunity to a new strain of a virus, it will spread much much faster, an easier.
