Answer:
b. $18,000, with $27,000 carried forward to 2020.
Explanation:
Capital loss deduction exists in order to encourage people to take the risk of investing their money. Through this deduction, you can save some money on your taxes, which would make your loss less damaging to your personal finances. If you have capital gains income, you can use these capital losses to offset the gains. On the other hand, if you have more capital losses than gains on a given year, you can claim up to $3,000 of those losses and deduct them against other type of income. If you still have more losses than that, you can carry the excess forward to the next year.
