Sandra acquired a passive activity three years ago. Until last year, the activity was profitable, and her at-risk amount was $300,000. Last year, the activity produced a loss of $100,000, and in the current year, the loss is $50,000. Assuming Sandra has received no passive activity income in the current or prior years, her suspended passive activity losses from the activity are: a. $90,000 from last year and $50,000 from the current year. b. $100,000 from last year and $50,000 from the current year. c. $0 from last year and $0 from the current year. d. $50,000 from the current year.
