C

Answer to Question 2

C
Ferguson Enterprises, a wholesaler who services the building and plumbing industry has used telemarketing on the in and out basis over the years. In-house sales are considered to be an important part of the entire Ferguson sales effort. Information is effectively transmitted to its current (or potential) consumers through well-trained personnel who understand the needs of the client base. A well-maintained database contributes to that industry understanding.
