Answer 1

Hint: HIV represents Human Immunodeficiency Virus, a microorganism that works by assaulting the human resistant framework. It has a place with a class of infections called retroviruses and all the more explicitly, a subgroup called lentiviruses, or infections that cause illness gradually.

Complete answer:
HIV is known as a retrovirus since it works in a back-to-front way. Dissimilar to different infections, retroviruses store their hereditary data utilizing RNA rather than DNA, which means they have to 'make' DNA when they enter a human cell so as to make new duplicates of themselves. HIV is a round infection. The external shell of the infection is known as the envelope and this is shrouded in spikes of the 'glycoproteins' gp120 and gp41, which permit HIV to bolt onto the CD4 receptor on CD4 T cells and enter the cell.

T helper cells play a main role in adaptive immunity. They not only help activate B cells to produce antibodies and macrophages to impair the ingested microorganisms, but also help activate cytotoxic T cells to kill infected target cells. HIV destroys (CD4 + cells) T helper cells, protecting you from common diseases and infections and staying healthy. As HIV gradually weakens your natural defenses, signs and symptoms will appear. Therefore, HIV attacks T helper cells.

Hence, the correct answer is option (C)

Note: The viral burden ought to stay imperceptible for at any rate a half year before relying upon this methodology as a viable HIV avoidance system. An individual must keep on having high adherence to treatment to keep up an imperceptible viral burden after some time.
