The correct answer is C, $200,000. The policy's principal sum is $100,000, and the double-indemnity provision pays twice that amount when death results from the stated qualifying accident: a commercial airplane crash. Because the insured was flying on a commercial flight and was killed in the crash, the maximum payable benefit is two times $100,000, or $200,000. The fact that the trip was to a business meeting does not reduce the benefit under the facts given. Choice A would be appropriate only if an exclusion applied, such as an excluded type of aviation activity. Choice B states only the policy's base amount and ignores the double-indemnity provision. Choice D incorrectly adds an additional amount beyond the stated double benefit. AD&D coverage pays only when the loss falls within the policy's accidental-loss definition and occurs within any stated loss period. Aviation wording matters: commercial passenger travel is commonly covered, while piloting, crew duties, private aircraft, or military aviation may be treated differently under the contract.
