Final answer:
Ryan's recognized gain on the contribution is $20,000.
Step-by-step explanation:
Ryan's recognized gain or loss on the contribution can be calculated by comparing the fair market value of the land ($21,000) with its adjusted basis ($1,000). The recognized gain or loss is the difference between these two values. In this case, Ryan's recognized gain would be $20,000 ($21,000 - $1,000). Therefore, the correct answer is (c) $20,000.
