Correct answer: D — Do not use the pen and arrange replacement supply

Frozen insulin may lose potency and should not be used. In this vignette, "Do not use the pen and arrange replacement supply" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
