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

The main problem with the influenza virus is that these viruses constantly changes their DNA, this allow them 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 influenza virus changes its genetic makeup after sometime, so 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 B.

Coaches will often urge athletes to exercise when they have a cold or other infection. What is the immunological reasoning behin

damaskus [11]

Exercise is the primary advice the coaches give to the athletes if they get a cold or any other infection. The main reason behind this advice is the fact that exercising strengthens the immunity of a person. When a person has an infection, the strengthening of the immune system will help his body to efficiently fight against the infectious pathogens. The blood circulation is increased which is involved in the enhancement of the acute immunity of the person.
