Under California Insurance Code Section 380, an "insurance policy" is defined as:

Why B is correct

Section 380 provides that a policy is a written contract of insurance. The requirement that the policy be written protects both parties by providing a complete, permanent record of the terms, including the parties, the coverage, the risks insured, the period of coverage, and the premium. An oral promise by an agent cannot substitute for the written policy, and the written application is only the insured's request for coverage. Because the policy is the contract, agents must ensure the written document accurately reflects what the client was promised during the sale.

Why the other options are wrong

• A) The policy must be a written contract. An oral promise is not a policy and cannot substitute for the written document that defines the coverage. An agent's spoken assurances can create expectations, but only the written policy constitutes the actual contract of insurance.
• C) The application is the insured's request for coverage. It is a solicitation document, not the insurance policy itself. The application invites the insurer to issue coverage; the policy, not the application, is the binding written contract.
• D) A binder is temporary evidence of coverage that precedes the formal written policy. It confirms pending coverage but is not the policy itself. A binder provides temporary evidence while underwriting is completed and is superseded by the formal policy.

Memory hook

Section 380: policy = paper. The deal is not real insurance until it is written down.
