Under the UCC firm‑offer rule, an offer by a merchant to keep an offer open for a stated time is irrevocable for that period, up to a maximum of three months unless consideration is given. A firm offer remains open for 45 days. If the buyer accepts after the firm offer expires, which statement is correct?

• A. A The offer remains irrevocable for 60 days
• B. B The offer remains irrevocable for 3 months
• C. C The offer is irrevocable only for 45 days
• D. D The offer is revocable immediately after 45 days

Answer: (C)

The firm-offer rule under the UCC means a merchant’s offer to keep something open is irrevocable for the time stated, but never longer than three months, and no extra consideration is needed. Here the stated open period is 45 days, which is shorter than the three‑month ceiling, so the offer remains irrevocable for 45 days. After that window passes, the offer can be revoked. If the buyer tries to accept after the 45 days, there isn’t an enforceable contract under that offer unless the merchant extends or revives the offer or a new offer is made. So the correct understanding is that the offer is irrevocable only for 45 days.
