The correct answer is A. The samurai warriors followed a code of honor called Bushido, that was specific for them, as they didn't share it with other warriors.
It was a strict and particular ethical code to which many samurai gave their lives, which demanded loyalty and honor until death. If a samurai failed to maintain his honor, he could recover it by practicing seppuku (ritual self-murder).
It was not simply a list of rules to which a warrior should adhere in exchange for his title, but a set of principles that prepared a man to fight without losing his humanity, and to lead and command without losing touch with values basic It was a description of a way of life, and a prescription to become a noble warrior and man.
