Vedclass · Answer

(A) Assertion $A$ is true because $AIDS$ ($Acquired$ $Immuno$ $Deficiency$ $Syndrome$) severely weakens the immune system,making the patient susceptible to opportunistic infections.Reason $R$ is true because the $HIV$ virus specifically targets and destroys helper $T$-lymphocytes ($CD4^+$ cells),which are essential for coordinating the immune response.Since the reduction in helper $T$-lymphocytes is the direct cause of the immune system's failure,Reason $R$ correctly explains Assertion $A$.

Assertion $A$: For an $AIDS$ patient,it becomes impossible to protect against infections from various diseases.
Reason $R$: $HIV$ infection leads to a decrease in the number of helper $T$-lymphocytes in the body.
Which option is correct for Assertion $A$ and Reason $R$?
