An organization sells 1,000 shares of its treasury stock at $15 per share previously acquired...

Treasury stock transactions are equity transactions, not income statement transactions. The organization originally acquired the treasury shares at $10 per share, so the treasury stock cost is $10,000. When it sells 1,000 shares at $15 per share, it receives cash of $15,000 and removes treasury stock at its $10,000 cost. The excess of $5,000 is credited to additional paid-in capital from treasury stock transactions. It is not recorded as a gain because treasury stock transactions do not create income. Option B is incorrect because treasury stock should be credited, not debited, when reissued. Option D is also incorrect. Therefore, Option C is correct.
