Which statement about HIV is correct?
Correct answer: D. It destroys helper T cells and progressively weakens immunity
- A. It can be cured with a course of antibiotics
- B. It survives for weeks on dry surfaces
- C. It is commonly spread by mosquito bites
- D. It destroys helper T cells and progressively weakens immunity
Explanation
HIV replicates inside helper T lymphocytes and destroys them, so immunity collapses and opportunistic infections follow. Antibiotics cannot touch a virus, the virus dies quickly outside the body, and mosquitoes do not transmit it.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
