Mark and Jesse had a joint life insurance policy which they purchased on the advice...

Comprehensive and Detailed in Depth Explanation with Exact Extract from Documents and Guides:

A joint life insurance policy can be either "first-to-die" or "last-to-die." TheIFSE Ethics and Professional Practice Course (Common Law)explains that a first-to-die policy pays the death benefit upon the death of the first insured, typically to the surviving insured, while a last-to-die policy pays upon the death of the second insured, often to a contingent beneficiary. Here, the policy’s purpose (to benefit the survivor for mortgage and expenses) suggests a first-to-die structure. However, Mark and Jesse died simultaneously in the crash. In such cases, the policy pays the full benefit to the contingent beneficiary (Louis) as if one death triggered the payout. The coverage is $450,000, not split (A), multiplied (C), or doubled (D). Thus, Louis receives $450,000, making B correct.
