Which of the following best describes "spiraling agreements" in negotiation?

Gradual concessions leading toward agreement is the correct understanding of "spiraling agreements" in negotiation because this term emphasizes a process whereby parties incrementally adjust their positions through a series of proposals and counterproposals. This dynamic creates momentum towards achieving a consensus, as participants are often more willing to make small concessions, building trust and fostering collaboration.

In this context, the iterative nature of negotiations allows both sides to gradually approach an agreement that reflects a balance of interests. As parties concede small amounts over time, the negotiations tend to create an environment conducive to compromise, ultimately steering them toward a mutually satisfactory resolution.

Other options describe different aspects of negotiation. For instance, referring to agreements that are finalized without further discussion overlooks the back-and-forth dialogue characteristic of spiraling agreements. The idea of revisiting previous issues iteratively could imply a more circular negotiation strategy, rather than the progressive movement implied in gradual concessions. Lastly, negotiating with only one party at a time does not align with the concept of spiraling agreements, which typically involves collaborative negotiation between all parties engaged. Thus, option B captures the essence of spiraling agreements effectively.
