Final answer:
The three basic sales tasks consist of conducting sales presentations, maintaining relationships with customers, and convincing potential buyers to make purchases. Strong communication skills can help reassure buyers who have imperfect information by providing detailed product information and other trust-building measures.
Step-by-step explanation:
The correct descriptions of the three basic sales tasks are: conducting effective sales presentations to potential buyers, building long-term relationships with existing customers, and identifying potential buyers and convincing them to make a purchase. Managing inventory and order fulfillment, although important, are generally considered separate from the core sales tasks listed above.
When it comes to reassuring a possible buyer who is faced with imperfect information, sellers can use various methods. Provided that they have strong communication skills, sellers may offer detailed product information, customer testimonials, warranties or guarantees, and provide samples or demonstrations. The goal is to create a level of trust and to provide enough information that the buyer feels comfortable making a decision.
