How does immune system fight viruses?
A
Immune system guards our body and when red blood cells which are the part of our immune system detect viruses in our body they kill the antigen or viruses by antibodies.
B
Immune system guards our body and when white blood cells which are the part of our immune system detect viruses in our body they kill the antigen or viruses by antibodies.
C
Immune system guards our body and when antibiotics which are the part of our immune system detect viruses in our body they kill the antigen.
D
None of above
Explanation: 

Detailed explanation-1: -The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen. The main cells of the immune system are lymphocytes known as B cells and T cells.

Detailed explanation-2: -Leukocytes patrol the blood and tissues throughout the body in search of intruders. When they detect a foreign substance, they send out signals and launch an immune attack. These disease-fighting cells are made in the bone marrow and are stored in many different places in the body such as the tonsils and adenoids.

Detailed explanation-3: -When the immune system detects an antigen, more white bloods cells are produced as well as antibodies. Then if an infection with that infective agent does occur, more antibodies can be produced quickly. White blood cells in the body remember how to fight the disease.

Detailed explanation-4: -When harmful microbes (tiny particles) enter and invade the body, the body produces white blood cells to fight the infection. The white blood cells identify the microbe, produce antibodies to fight it, and help other immune responses to occur.
