Which example represents a clear business-purpose loan?

The choice that represents a clear business-purpose loan is the example of buying equipment for a bakery. This is because a business-purpose loan is specifically intended for use in a commercial or business-related endeavor. In this case, acquiring equipment necessary for operating a bakery directly aligns with business activities, as it contributes to the production of goods and services for the bakery.

In contrast, financing a family vacation, purchasing a new family car, or taking out a personal loan for education all pertain to personal or consumer purposes. These experiences and purchases do not generate revenue or facilitate business operations, which is a key distinction that marks the boundaries between personal loans and business-purpose loans under Regulation Z.
