Final answer:
Karen's realized and recognized gain on the sale of the land is $10,000.
This correct answer is B.
Step-by-step explanation:
Karen's realized gain on the sale of the land is $10,000 and her recognized gain is also $10,000.
Realized gain is the difference between the selling price and the adjusted basis of the property. In this case, Karen sells the land for $110,000, which is $6,000 more than what Elbert gave it to her for ($104,000 - $90,000). So the realized gain is $6,000.
However, since Karen received the land as a gift from Elbert, the recognized gain is calculated based on Elbert's adjusted basis of $100,000. Since the selling price of the land is higher than Elbert's adjusted basis, the recognized gain is equal to the realized gain of $6,000.
This correct answer is B.
