Correct answer: Some viruses create lasting immune memory while others mutate frequently or have many strains.

Explanation: Varicella‑zoster virus (chickenpox) typically induces a strong, long‑lasting adaptive immune response (memory B and T cells and neutralizing antibodies), so you rarely get chickenpox again (reactivation causes shingles, not a second primary). "Common cold" illnesses are caused by many different viruses (rhinoviruses, coronaviruses, adenoviruses, etc.) with dozens or hundreds of distinct strains and frequent antigenic change, and mucosal immunity to these often wanes — so people can catch colds repeatedly. The other options are oversimplified or incorrect.
