Choice "C" is correct. First, the long-term capital gain of $14,000 is netted with the long-term capital loss of $8,000. This results in a net long-term capital gain of $6,000. Next, the short-term capital gain of $6,000 is netted with the short-term capital loss of $4,000. This results in a net short-term capital gain of $2,000. Now add the net long-term capital gain of $6,000 and the net short-term capital gain of $2,000 to arrive at a net capital gain of $8,000. This amount is reduced by the $5,000 worthless stock. So the final net capital gain is $3,000. Note that the Section 1244 loss of $10,000 does not affect this calculation because it is an ordinary loss and not a capital loss.Choices "b", "a", and "d" are incorrect per the above explanation.
