Final answer:
Pluto Inc. obtains its clients through solicitation by making cold calls, sending promotional letters, and actively following up on leads.
Step-by-step explanation:
Pluto Inc., a new ad agency, is obtaining clients through solicitation. The company uses cold calls, promotional letters, and follows up on leads, which are all direct methods of contacting potential clients in order to offer services. Maintaining a separate department for the purpose of bringing in new accounts indicates a structured strategy to solicit business, which involves active outreach rather than passive methods like referrals, public relations, or reputation management.
