Which of the following would not be a promise statutorily made enforceable without consideration?

A) Hawkins, in good faith, changes the quantity of square yards of carpet ordered from Grant Mills.
B) Jones promises to pay his cousin's past-due cell phone bill.
C) Dodds signs and delivers a waiver of a claim arising out of a breach of contract by Keys.
D) A signed, written offer by Marcum Jewelers to sell four dozen 18" gold chains to the Alpha Sorority for $480 within the next 30 days.

Jones's promise to pay his cousin's past-due cell phone bill does not fit into the categories of promises that are made enforceable by statute without consideration. The other options (A, C, D) involve modifications of existing agreements, waivers of claims, and firm offers in a commercial context, which can be enforceable without consideration under certain statutes like the Uniform Commercial Code (UCC). However, a promise to pay someone else's debt, as in option B, typically requires consideration to be enforceable unless it falls into a specific exception, which is not indicated by the information provided.
