Final answer:
The most likely revenue center for Bernaise, Inc. is a retail store in Dallas because a revenue center is part of a company that directly contributes to its revenue through sales. Option A is correct.
Step-by-step explanation:
A revenue center for Bernaise, Inc., which sells cosmetic products in the United States, is most likely A) a Bernaise retail store in Dallas. A revenue center is a segment of a business that is responsible for revenue generation. In this case, the retail store directly sells products to customers, which is the primary source of revenue for the company.
This differs from options B and D, like the human resources department which doesn't generate revenue but instead manages company personnel, or the product lines which represent what the company sells, not where or how it sells those products. Option C, a kiosk, is also a direct sales point but the question specifies 'most likely', and typically retail stores generate more revenue than kiosks due to their larger size and inventory capabilities.
