Correct answer: A — Discard the bottle according to the labelled after-opening period

Eye drops can become contaminated after opening, and many multidose preparations have a limited in-use period. Writing the opening date is good practice but does not extend the safe-use period. The pharmacist should reinforce correct storage and timely replacement.
