1. Which of the following limited opportunities for freedom in the South after the Civil War ended?

a. Radial Reconstruction
b. Lincoln's Ten Percent Plan
c. the Black Codes
d. the Fourteenth Amendment

The correct answer is c. The Black Codes limited opportunities for freedom in the South after the Civil War ended. The Black Codes were laws passed by Southern states to restrict the rights and freedom of African Americans, often through segregation and discriminatory practices. The Radical Reconstruction and Lincoln's Ten Percent Plan were efforts to rebuild and reconstruct the Southern states after the Civil War and provide greater political and civil rights for African Americans. The Fourteenth Amendment to the US Constitution was also aimed at guaranteeing equal protection under the law for all citizens, regardless of race.
