Final answer:
Wholesalers typically buy products from manufacturers and sell to retailers, while sometimes selling in bulk directly to consumers. They also offer additional services such as market information and financial assistance to retailers.
Step-by-step explanation:
The question pertains to the role of wholesalers in the distribution chain. Let's examine the given options:
a. Help manufacturers sell their products directly to consumers. - This is typically not the role of wholesalers, as they usually do not sell directly to consumers but rather to retailers.
c. Buy products from manufacturers and sell to consumers. - While wholesalers can sell to consumers, this is not their primary function.
d. Provide promotion, market information, and financial assistance to retailers. - Wholesalers do provide these services to retailers to help them sell the manufacturers' products more effectively. Reflecting on the roles of wholesalers within a market system, they are crucial in connecting manufacturers with retailers (or sometimes directly with consumers), and maintaining a flow of goods. Additionally, they may play a role in providing market information and financial assistance to retailers, enhancing the overall distribution process.
