How did the enclosure movement change the economy in the early tudor period in england? a. it undermined the lords' source of authority. b. it caused the price of land to rise. c. it made agriculture untenable in england. d. it created a large, new pool of urban labor?

The enclosure movement created a large pool of urban labor, so the answer is D. The enclosure movement meant that the open fields were "enclosed" (basically they divided and partitioned with hedges and fences)  and they were not open any more for the public use. This led to people to move to the cities in search for work.
