A policy cannot be issued without the applicant's:

The correct answer highlights the essential components required for a life insurance policy to be valid and enforceable. Consideration refers to the initial premium payment made by the applicant, which signifies the applicant's commitment to the contract. This payment is a fundamental principle of contract law—the insurer must receive something of value in exchange for providing coverage.

Additionally, signatures from the applicant are necessary to confirm their agreement to the terms and conditions of the insurance policy. The applicant's signature reflects their acknowledgment of the information provided in the application, such as personal details, health history, and other disclosures.

In contrast, insurable interest, while crucial for validating the insurance contract, is typically assessed at the time of application and does not need the applicant's explicit demonstration within the application material itself. A beneficiary's signature is not required for the policy to be issued, as it's the policyholder's obligations that must first be satisfied. The agent's countersignature, while important for certain types of policies, is not a universal necessity for the issuance of life insurance contracts. Therefore, having consideration and signatures from the applicant clearly establishes the policy's legitimacy and commitment, making it the correct choice.
