The correct answer is D. Look after the welfare of present and future generations
Explanation:
The excerpt presented from the Iroquois constitution provides mainly a description of the desirable traits and behavior a great leader should have, this includes a calm temper "Neither anger nor fury shall find lodgement in your mind"; avoid following only self-interest "n your efforts at law making, in all your official acts, self-interest shall be cast into oblivion" and especially always listen to the people and guaranteed their welfare "Look and listen for the welfare of the whole people" besides this, the constitution emphasizes the welfare should be preserved "not only the present but also the coming generations". Considering the previous ideas the trait a great leader should have according to the excerpt is that the leader should look after the welfare of present and future.
