The statement that MOST accurately represents the major difference between the Japanese and European feudal systems is:
"In Europe, feudal lords protected peasants in exchange for part of their crops. In Japan, feudal lords protected peasants without asking anything in return."
This statement highlights the economic and reciprocal nature of the feudal relationships in Europe compared to the more hierarchical and loyalty-driven relationships in Japan. While the other options touch on aspects of religion and code of behavior, the first statement addresses a key aspect of the economic arrangements that defined the feudal systems in each region.
