The correct answer is C. Blocks itself from dealing with other brokers on the risk . The first-in principle is a market practice used by some insurers when more than one broker approaches them for the same account.
Under this principle, the first broker who submits the risk to the insurer is recognized as having access to that market for that specific account. The insurer will then generally decline to quote or negotiate with later brokers on the same risk unless proper authority changes or market-release procedures are followed. This avoids duplicated underwriting work, conflicting submissions, and disputes between brokers. It also encourages brokers to secure proper client authorization before approaching markets. The insurer does not simply cooperate with the largest brokerage, because that would be unfair and inconsistent with orderly market conduct. It also does not issue sequential quotations to every broker, because that could lead to confusion and inconsistent terms. The first-in principle is about market control and broker recognition for a specific submission.
