Which of the following is a component of the transactional function in marketing channels?

The transactional function in marketing channels is primarily concerned with the activities involved in facilitating the sale and transfer of ownership of goods and services. Buying and selling products are core aspects of this function because they represent the direct interactions that occur between buyers and sellers. This includes negotiating prices, closing sales, and completing transactions, which are all essential elements of commerce.

In this context, transporting goods relates more to the logistical aspects of moving products from one location to another, and assorting products refers to organizing a variety of products in a way that makes sense for consumers, both of which fall under different functions within marketing channels. Evaluating customer preferences is more aligned with the planning and strategy components of marketing, rather than the transactional aspect focused on direct purchasing and selling.
