The refusal of doing business with an individual or business is called a(n):

The term that describes the refusal to do business with an individual or organization is correctly identified as a boycott. In the context of insurance and financial transactions, a boycott involves intentionally avoiding or refusing to transact with a particular provider or client. This can arise from various reasons, such as concerns regarding risk, compliance issues, or ethical considerations.

Understanding the implications of a boycott is crucial within the realm of insurance, as it can affect market dynamics, consumer access to products, and overall industry competition. Boycotts can be based on a variety of factors like discriminatory practices or unresolved disputes, and they have significant legal and reputational consequences for both the entity enacting the boycott and the entity being boycotted.

In contrast, terms like exclusion, denial, and decline carry different meanings. Exclusion typically refers to specific limitations or restrictions within an insurance policy. Denial indicates a refusal of a claim made against a policy. Decline usually refers to an underwriter's decision not to accept an application for coverage. Each of these terms involves specific processes and implications that differ markedly from the broader concept of a boycott.
