What is the consideration required by a life insurance company to make coverage effective?

The correct choice is the payment of the initial premium. In order for a life insurance policy to become effective, the insured typically must pay the initial premium at the time of application or within a specified period thereafter. This initial payment is what activates the coverage and signifies the applicant's commitment to the contract with the insurance company. Without this payment, the insurer has no obligation to provide coverage, as the premium serves as a fundamental consideration in the insurance contract.

The other options do not fulfill the necessary prerequisite for making the coverage effective. Although payment of renewal premiums is important for maintaining coverage, it does not apply to the initial effectiveness of the policy. The promise to act in good faith is also crucial in insurance transactions (as it relates to the duty of both parties to uphold the integrity of the contract), but it is not a direct consideration for the policy's activation. Lastly, the beneficiary's insurable interest is indeed a requirement for the validity of a policy, but it relates more to the legitimacy of the beneficiary's claim than to making the coverage effective at the outset.
