Final answer:
Article 2 of the UCC applies to Vin Diesel's purchase of a toupee, as it deals with the sale of tangible personal property.
Step-by-step explanation:
The purchase made by Vin Diesel for a toupee falls under Article 2 of the Uniform Commercial Code (UCC) which deals with the sale of goods. Article 2 applies to transactions involving the sale of tangible personal property. A toupee, being an item that is movable at the time of sale and used for personal use, qualifies as a good. Since Article 2 covers the sales of goods, it would govern the terms and conditions of the transaction, including warranties, buyer's and seller's remedies, and other contractual obligations.
