Final answer:
Allison will be able to deduct b) $3,200 of her losses.
Step-by-step explanation:
Allison will be able to deduct $3,200 from her losses. According to the IRS, gambling losses can be deducted, but only to the extent of gambling winnings. In this case, Allison won $3,200 in the Kentucky Derby, so she can deduct that amount from her losses. This means she can deduct the full amount of her losses, which is $5,000, up to the amount of her winnings. However, it's important to note that Allison will need to have documentation that verifies her losses. This could include records of her bets, receipts, or other forms of documentation provided by the racetrack. Without proper documentation, she may not be able to claim the deduction.
