Question

how did tokugawa ieyasu limit the power of the daimyo? by reclaiming all land owned by the daimyo by limiting the amount of land they could own by giving the daimyo more land by purchasing all land owned by the daimyo at double its value

Explanation:

Tokugawa Ieyasu limited the power of daimyo by limiting the amount of land they could own. Reclaiming all land (Option 1) is too extreme and not in line with historical records. Giving more land (Option 3) would not limit power. Purchasing at double value (Option 4) is not a historical measure. Limiting land - ownership (Option 2) was a practical way to control daimyo's economic and military potential (as land was related to resources and retainers).

Answer:

B. By limiting the amount of land they could own
