Correct Answer: D

Rationale: Storing Varivax, a vaccine for varicella (chickenpox), in the freezer at -50°C to -15°C is appropriate as it helps maintain its efficacy and stability over time, ensuring the vaccine remains effective when administered.

Valsartan (A) and Varenicline (C) are medications that do not require such low temperatures for storage and can lose potency if frozen. Vardenafil (B), a treatment for erectile dysfunction, also does not need freezing and may degrade under such conditions. Therefore, Varivax is uniquely suited for long-term storage in these low temperatures.
