Answer:
b. $20,000: $250,000
Step-by-step explanation:
The computation is shown below:
The passive activity rules at the opening of 2021 would be equivalent to the amount given i.e. $250,000
And, the suspended amount would be
= $100,000 + $80,000 + $90,000 - $250,000
= $270,000 - $250,000
= $20,000
Hence, the correct option is b.
