Correct answer: C — Keep unopened pens refrigerated and protect in-use pens from heat

Insulin should be stored according to manufacturer guidance, with unopened stock refrigerated and in-use pens kept within permitted temperature limits. Heat or freezing can reduce effectiveness. In this scenario, the correct option is keep unopened pens refrigerated and protect in-use pens from heat. The other options are plausible but do not address the key clinical, legal or safety issue as directly. This aligns with UK pharmacy practice guidance cited in the reference field.
