Answer:
b. Scotty did not itemize deductions in 2017
Explanation:
Let's assume that Scotty didn't itemize in 2015, that means that he will be able to remove the reimbursement from gross income in 2016. Also, assuming Scotty itemized deductions in 2015, he has to report the reimbursement as gross income in 2016 to the extent he received a tax benefit from deducting medical expenses in 2015. If he itemized in 2016 there will not be an impact on the treatment of the reimbursement.
