Final answer:
The correct answer is that the UCC does not prescribe a specific means of acceptance option (a) and allows for flexibility as long as the acceptance does not materially alter the offer's terms.
Step-by-step explanation:
The approach taken by the Uniform Commercial Code (UCC) toward the proper means of acceptance is quite flexible. Specifically, the UCC does not prescribe a single, specific means of acceptance. This makes option A correct.
Furthermore, the UCC is not silent on the issue (option B), as it provides general guidelines for acceptance. It does not require acceptance to be in writing (option C), as the UCC accommodates various forms of acceptance.
Lastly, option D is incorrect because the UCC does not mandate oral acceptance either. Instead, the UCC adheres to the notion of the 'mirror image rule' less strictly than common law and allows for acceptance to be actionable unless the acceptance materially alters the terms of the offer.
