Answer:
The correct answers are B and D. The Radical Republicans in Congress wanted to grant voting rights to former slaves to gain more votes for the Republican Party, and to ensure that everyone had access to basic rights.
Step-by-step explanation:
The Radical Republicans formed an American political movement within the Republican Party from 1854 until the end of the Reconstruction in 1877. They called themselves the "radicals" and were opposed during the war to the moderates and to the conservatives led by Abraham Lincoln and, after the war, to the ex-Confederate conservatives and the liberals of the Union.
Radical Republicans strongly opposed slavery during the war and subsequently mistrusted the former Confederates. They demanded harsh measures against the former rebels and insisted on the need to grant civil rights and the right to vote to freed slaves, in order to grant them the rights they were treating to assure, and as a way to put a limit to former Confederates.
