Correct answer: C — keep unused pens in the fridge and avoid freezing or direct heat

Unused insulin pens should generally be stored in the refrigerator according to product instructions and protected from freezing. Exposure to excessive heat can reduce insulin potency. In-use pens may have separate room-temperature limits, but spare pens should remain refrigerated. The patient should be advised to transport them home promptly and avoid direct heat.
