The key to selling and negotiating is seeking to:

A) identify gatekeepers.
B) create a win-win situation.
C) provide all product information.
D) generate profitable, one-time sales.
E) understand significant group behaviors.

The key to successful selling and negotiating is to create a win-win situation, where both parties involved feel satisfied with the outcome. This often involves finding common ground and compromise in order to reach a mutually beneficial agreement. Simply seeking to generate profitable one-time sales or providing all product information may not lead to long-term success. While understanding group behaviors may be helpful in some contexts, it is not always necessary for effective selling and negotiating. Identifying gatekeepers may be important in some industries, but it is not the key to success in all sales and negotiation situations.
