During Japan's feudal period, the MAIN role of the samurai was to protect the daimyos and their kingdoms.

Option D

Explanation:

The samurai's in the feudal period of Japan were warriors whose role was to protect the daiymos and their kingdom by fighting in battle when needed with their accustomed battle gadget. The samurai were brave warriors skilled in the art of martial art, performed dances in the stealth of a battle, wining their opponent with their swords.

The samaurai carried with them two well made swords, these samurai's were skilled in swordmanship and were well handed in the skill, with their skill, agility and proficiency the samurai's in the Japanese feudal period protected the jaimyos and their kingdoms.Once civilization reached they were disbanded and sent into different acts like, businessmen, etc.    

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
