Answer 1

Answer:

Hiv selectively infects and kill b lymphocytes

Answer 2

The wrong statement regarding AIDS is that (c) HIV selectively infects and kills the B-  lymphocytes

• AIDS is caused by the human immunodeficiency virus (HIV) Retrovirus possesses the genome of RNA that undergoes reverse transcription and is thus converted to DNA.
• HIV targets CD-4 T cells selectively, as a result of which their count decreases markedly. CD-4 counts in the case of advanced HIV infection are below 200 cells per cubic millimetre.
