The correct answer is A. 30 days.

In general, the Beyond-Use Date (BUD) for an opened multi-dose vial, unless otherwise specified by the manufacturer, is typically 30 days. This standard duration ensures the sterility and stability of the medication within the vial for a reasonable period after opening. It is essential to adhere to these guidelines to maintain patient safety and efficacy of the medications being dispensed.

Options B, C, and D (28 days, 21 days, 14 days) are incorrect as they do not align with the standard BUD for opened multi-dose vials in the absence of any special manufacturer recommendations.
