Answer: The correct answer is "d. A capital loss of $30,000 and an ordinary loss of $50,000.".
Explanation: With respect to the sale, Art has: A capital loss of $30,000 and an ordinary loss of $50,000.
For the shares of $ 1244 the basis is $ 120000, when Art sells the shares at $ 50,000 the loss is $ 70,000 but as Art is not married the ordinary loss that corresponds to it is $ 50,000 and $ 30,000 correspond to the remaining capital loss.
