Final answer:
Option (c), Sally, the former beneficiary, received the benefit of the life insurance policy after Adam's death, as she remained the named beneficiary following the absolute assignment of the policy to Adam.
Step-by-step explanation:
Upon Adam's death, the benefit of the policy is paid out to the named beneficiary at the time of his passing. Since Nellie made an absolute assignment of the policy to Adam when he reached the age of majority, he became the owner of the policy.
Given that Adam did not change the beneficiary after the policy was assigned to him, the beneficiary designation remained the same. Therefore, the person who received the benefit of the policy would be Sally, the former beneficiary, as she was the named beneficiary at the time of Adam's death.
