Answer: c. Currency loss from closing of a foreign subsidiary.
Step-by-step explanation:
GAAP refers to the industry standard and it gives a clear view of the operations of a business from a financial point of view. On the other hand, the non-GAAP disclosure deviates from the industry standard and in such case, adjustments are made to show company's operations.
The non-GAAP disclosures which is least likely to create variance between GAAP and non-GAAP operating income is the currency loss from closing of a foreign subsidiary.
