Vedclass · Answer

(A) $AIDS$ (Acquired Immuno Deficiency Syndrome) is caused by the Human Immunodeficiency Virus $(HIV)$.$HIV$ specifically targets and infects helper $T$-lymphocytes ($CD4^+$ cells).As the virus replicates within these cells,it leads to a progressive decline in the count of helper $T$-cells.Since helper $T$-cells are crucial for coordinating the immune response,their depletion severely weakens the body's defense system,making the individual susceptible to opportunistic infections.
