Final answer:
Wealthy landowners were ranked in the Japanese feudal system based on the amount of rice they collected from peasants.
Step-by-step explanation:
In the Japanese feudal system, wealthy landowners were ranked based on the amount of rice they collected from peasants.
The land allocated to wealthy landowners varied depending on their relationship to the ruler and their loyalty. The most fertile and valuable rice-producing land was given to the loyal daimyos, who were either related to the ruler or had declared their loyalty before a significant battle. The land given to the daimyos who had become loyal after the battle or fought against the ruler was less fertile or farthest away from the capital.
Therefore, the answer is d. Based on the amount of rice they collected from peasants.
