The insurer will pay $100,000, the base policy death benefit only. An accidental death benefit rider pays an additional benefit only if death results from a covered accident as defined in the rider. A heart attack is generally a death by sickness or natural cause, not accidental bodily injury, even if it occurs while the insured is traveling to work. Therefore, the rider is not triggered. If the insured had died in a covered accident, the rider might have doubled the benefit under a common double-indemnity structure, resulting in $200,000. But the facts do not support that result. Option B and option D have no basis in the stated policy values. Option C is the trap because accidental death riders often double the benefit, but only when the cause of death qualifies under the rider. The key exam distinction is cause of death: accidental death rider = accident-caused death, not illness-caused death.
