Question 32 HIV is: A A malignancy associatec with AIDS B A drug used to treat AIDS C The virus that causes AIDS D The test used to detect AIDS E A type of lymphoma

The correct answer is:<br /><br />**(C) The virus that causes AIDS**<br /><br />### Explanation:<br />- **HIV (Human Immunodeficiency Virus)** is the virus responsible for causing **AIDS (Acquired Immunodeficiency Syndrome)**. <br />- HIV attacks the immune system, specifically targeting CD4 cells (T-helper cells), which are crucial for fighting infections. Over time, if untreated, HIV can lead to a severely weakened immune system, resulting in AIDS.<br /> <br />#### Why the other options are incorrect:<br />- **(A) A malignancy associated with AIDS**: This refers to conditions like Kaposi's sarcoma or certain lymphomas, which are opportunistic diseases associated with AIDS but not HIV itself.<br />- **(B) A drug used to treat AIDS**: Drugs such as antiretroviral therapy (ART) are used to manage HIV/AIDS, but HIV is not a drug.<br />- **(D) The test used to detect AIDS**: Tests like ELISA or Western blot are used to detect HIV infection, not AIDS directly.<br />- **(E) A type of lymphoma**: Lymphomas may occur as complications of AIDS, but they are not HIV.<br /><br />
