Answer:
Gain recognized by Tom is $10000
So option (b) will be correct answer
Explanation :
We have given liability on bulding assumed by Paul Corp = $30,000
Tom's adjusted basis in the building = $20,000
Since the liability assumed by Paul Corp on the building is greater than Tom's adjusted basis, Tom must recognize gain equal to the difference between the liability on the building and his adjusted basis.
So gain recognized by Tom = $30,000 - $20,000 = $10,000
