Read the followinf statement :

Statement I:  AIDS is a disorder caused by HIV.

Statement II:  HIV is a virus that damages immune system of its host.

Both statement I and statement II  are correct .

The correct answer is Option (3) - Both Statement I and Statement II are correct.

Explanation:

AIDS (Acquired Immunodeficiency Syndrome) is a disorder caused by the Human Immunodeficiency Virus (HIV). HIV is a virus that specifically targets and infects cells of the immune system, particularly CD4⁺ T cells, which play a crucial role in the body's immune response.

Once inside the host's body, HIV replicates and gradually weakens the immune system, impairing its ability to fight off infections and diseases. Over time, as the immune system becomes progressively compromised, the individual becomes more susceptible to opportunistic infections and certain types of cancers. This advanced stage of HIV infection is known as AIDS.

Therefore, HIV infection leads to the development of AIDS, which is characterized by severe immunodeficiency and the increased susceptibility to various infections and diseases. HIV damages the immune system by replicating within immune cells, destroying them in the process, and interfering with the normal functioning of the immune response.
