Antibiotics target bacteria, not viruses

Steps:

• Identify HIV as a viral infection caused by the human immunodeficiency virus.
• Recall that antibiotics are medications designed to kill or inhibit bacteria.
• Note that viruses replicate inside host cells using the host's machinery, unlike independent bacterial cells.
• Conclude antibiotics cannot interfere with viral replication processes.

Why B is correct:

• Antibiotics specifically target bacterial cell structures like peptidoglycan walls or protein synthesis ribosomes, which viruses lack as they are non-cellular entities.

Why the others are wrong:

• A: Viral size does not determine antibiotic efficacy; mechanism of action does.
• C: Viral composition of protein and DNA/RNA is irrelevant to antibiotic targeting.
• D: Viruses are pathogens, as HIV causes AIDS by attacking the immune system.

Final answer: B
