The correct answer is option 1, Lymphocytes. The AIDS virus, also known as HIV (Human Immunodeficiency Virus), primarily targets and destroys a specific type of white blood cells called lymphocytes. Lymphocytes are a crucial component of the immune system and play a vital role in defending the body against infections and diseases. By attacking and killing lymphocytes, the AIDS virus weakens the immune system, making the individual more susceptible to various opportunistic infections and diseases. While the virus can also affect other types of white blood cells, such as monocytes, neutrophils, and basophils, it predominantly affects lymphocytes. It`s important to note that the destruction of lymphocytes by the AIDS virus is one of the main reasons why HIV infection can lead to the development of acquired immunodeficiency syndrome (AIDS).
