A.
HTLV acts by overstimulating the immune system unlike HIV,which causes immune suppression.
Both HIV and HTLV belong to the family "Retroviridae"...so they both will have reverse transcriptase enzyme...pls correct me if im having wrong concept.

A is the correct answer. HIV causes a lytic infection of T cells. Both HTLV and HIV are retroviruses. However, HTLV is an oncovirus, whereas HIV is a lentivirus. HTLV causes a slow, transforming infection, whereas HIV causes a lytic infection of the CD4 T cells. As a result, the nature of the diseases is extremely different.
