Choice "D" is correct. The costs of organizing the corporation are expensable (subject to the $5,000 limitation) and amortizable, but the costs of selling stock are not. The only expense listed that qualifies for expense/amortization is the legal fees for drafting the corporate charter; the others relate to the sale of stock.
Choices "a", "c", and "b" are incorrect. These are expenses of selling the corporation's stock and are not a cost of organizing the corporation and therefore cannot be amortized.
