B Correct answer
Explanation

Viruses replicate inside host cells using the host's own machinery, making it extremely difficult to develop drugs that target the virus without harming human cells. Bacteria, fungi, and protozoa have their own cellular structures and metabolic pathways that can be selectively targeted with fewer side effects.
