Answer:
The Answer is C. Processing Returns.
Step-by-step explanation:
First, lets try to understand the question.
Who is a distributor? simple, a distributor is an agent that supplies goods of a manufacturer to retailers.
So, option A is correct. They do provide Info and advice.
option B is correct as well. They provide credit and delivery for purchases.
Option D is acceptable as well! Since the distributors are supplying to the retailers, they are indeed selling at wholesale costs.
So, What about C? Processing Returns? Let's take an example. You buy a product from Walmart. If there is a problem with the product, who do you contact? Its either Walmart or the Manufacturer who's contact details are available on the package right? Not to the one who distributed products to the Walmart.
