In this context, when does the expiration date occur?

• A. End of the month
• B. First day of the month
• C. Last day of the month
• D. The date of manufacture

Answer: (C)

The expiration date is set to the last day of the month shown. This means the product is considered good through that final day, and it officially expires when that day ends. Having the expiry tied to the end of the month gives a clear, uniform shelf-life window within one calendar month, which helps with stock rotation and planning. The manufacture date only tells when it was produced, not when it should be discarded, and starting the window at the first day of the month would create awkward half-month periods.
