Answer: E. user
Explanation:
A Buying Center refers to the members of an organization that finalize purchase decisions.
At the basic level, there are typically six roles within buying centers which include, Initiators, Influencers, Buyers, Deciders, End Users and Gate Keepers.
We will focus on the End Users which is where the person the salesman heard is most likely to be.
The Users are the people who will end up actually using the product as the man insinuates when he mentions that he needs it to work.
The Users also initiate the purchase process which is what the man is attempting to do.
Other roles of the Users include the generation of the purchase specs and evaluation of product performance after the purchase has been done.
If you need any clarification don't hesitate to comment or react. Cheerio.
