The following excerpt is from a speech by abraham lincoln. which line implies that lincoln tried to convince southerners that they were responsible for the growing conflict in the nation by defending slavery?

my countrymen, one and all, think calmly and well upon this whole subject. nothing valuable can be lost by taking time. if there be an object to hurry any of you in hot haste to a step which you would never take deliberately, that object will be frustrated by taking time; but no good object can be frustrated by it. such of you as are now dissatisfied still have the old constitution unimpaired, and, on the sensitive point, the laws of your own framing under it; while the new administration will have no immediate power, if it would, to change either if it were admitted that you who are dissatisfied hold the right side in the dispute, there still is no single good reason for precipitate action. intelligence, patriotism, christianity, and a firm reliance on him who has never yet forsaken this favored land are still competent to adjust in the best way all our present difficulty.

in your hands, my dissatisfied fellow-countrymen, and not in mine, is the momentous issue of civil war. the government will not assail you. you can have no conflict without being yourselves the aggressors. you have no oath registered in heaven to destroy the government, while i shall have the most solemn one to "preserve, protect, and defend it."

i am loath to close. we are not enemies, but friends. we must not be enemies. though passion may have strained it must not break our bonds of affection. the mystic chords of memory, stretching from every battlefield and patriot grave to every living heart and hearthstone all over this broad land, will yet swell the chorus of the union, when again touched, as surely they will be, by the better angels of our nature.

a. if it were admitted that you who are dissatisfied hold the right side in the dispute,

b. in your hands, my dissatisfied fellow-countrymen, and not in mine, is the momentous issue of civil war.

c. you have no oath registered in heaven to destroy the government, while i shall have the most solemn one to "preserve, protect, and defend it."

d. we are not enemies, but friends. we must not be enemies
