Final answer:
The Civil War came to be remembered as a war of "brother against brother" and divided the nation along regional lines. Although it eventually led to the abolition of slavery, it was not initially seen as a turning point toward racial equality or liberation for blacks.
Step-by-step explanation:
The Civil War came to be remembered by the 1890s as a war of "brother against brother" (option b). The conflict had deeply divided the nation along regional lines, with families and communities finding themselves on opposing sides. This phrase captured the human toll and personal sacrifice experienced during the war. While the war did ultimately lead to the abolition of slavery, it was not until much later that it came to be seen as a turning point toward racial equality (option a) or as the war that liberated blacks from slavery (option c).
