What Was the State of the Economy During Grant's Second

What was the state of the economy during Grant's second term, and why was this significant?

A) The economy experienced a mild panic, but Grant quickly set it back on track, which helped his standing within the Republican party, guaranteed him the nomination in the upcoming election, and made Reconstruction appear more likely to succeed.
B) The economy stayed relatively similar to that of the Civil War because Grant refused to eliminate war bonds out of fear that it would have detrimental effects on an already-fragile southern infrastructure, and as a result, many southern politicians began to support him.
C) A severe depression resulted from Grant's efforts to withdraw greenbacks, or paper money, from circulation after the war, which intensified the debate over soft-money versus hard-money currency and helped enable Democrats to overtake the Republicans in the congressional elections.
D) The northern and southern economies became exceedingly integrated as industrialization spread throughout the South, and as a result, southern farmers began to take steps to bring about deflation as a means of returning to their old way of life.
E) The economy flourished under Grant because he had the foresight to introduce greenbacks into circulation for the first time, and as a result, politicians were more willing to consider and implement his policies regarding protections for African Americans.
