Answer:
C) smaller because supply is more elastic over time.
Step-by-step explanation:
Since the total quantity supplied of new homes had decreased so much during the last recession, the quantity demanded exceeded the supply by far, which causes a shortage that results in a price increase.
As the demand for new homes grows and stabilizes, the suppliers of new homes will adjust their production levels to satisfy the increase in demand. Since the supply is generally very elastic, the price of new homes should also stabilize and future price increases (if any) should be smaller.
