The correct option is:
B. Northerners who tried to make money off the dire situation in the South and Southerners who did the same.
The name “carpetbaggers” points to Northerners who traveled to the South after the Civil War, throughout Reconstruction. Many carpetbaggers were believed to have moved South for their own economic and political profits.
Scalawags were white Southerners who also cooperated politically with former slaves and the Northern newcomers.
