Answer:
B. Radical's
Step-by-step explanation:
The plan that called for a military occupation of the South was Radical's plan. The Radical Republicans, led by Thaddeus Stevens and Charles Sumner, sought a more punitive and harsh approach towards the Southern states following the Civil War. Their plan, known as the Reconstruction Acts of 1867, divided the South into five military districts and imposed military rule over the region until certain conditions were met, such as ratification of the 14th Amendment and granting voting rights to African American men.
