Mr. Robertson signed up for a life insurance plan at work which required him to list a beneficiary. The contract stated that he could only change the beneficiary each year during the open window for changes which was December 1 thru 31st. Initially Mr. Robertson selected his wife Caroline as his beneficiary, but in June, they were divorced. A few days later, Mr. Robertson notified his employer in writing that he wanted to change the beneficiary to his son Harry. The employer made note of the change. In October, Mr. Robertson passed away and the insurance company paid the claim to Mr. Robertson's ex-wife Caroline. His son Harry sued. What is the likely outcome?

a. Harry should receive the money because his father's intentions were in writing.

b. Caroline should receive the money because the company failed to make the authorized change.

c. Harry should receive the money because the money was assigned to him.

d. Caroline should receive the money because Mr. Robertson did not make the changes within the specified time period.
