Final answer:
Rubio can deduct $15,350 of his $22,650 loss from the limited partnership, which is limited to his at-risk amount.
Step-by-step explanation:
The question pertains to the deductibility of a loss from a limited partnership interest considering tax basis and at-risk limitations. Rubio invested $20,500 in a limited partnership and has an at-risk amount of $15,350. Given Rubio's share of the limited partnership loss for the year is $22,650, the deduction of this loss is limited to the at-risk amount, which is the amount he can actually stand to lose in the investment. Therefore, the correct answer is B. $15,350, limited to the at-risk amount. Any loss beyond the at-risk amount is not currently deductible.
