Explanation:

Andrew Johnson was the 17th President of the United States succeeding after the assassination of Abraham Lincoln. He served in the office from 1865-1869 and was assumed after the assassination of President Abraham Lincoln as he was the Vice-President at that time.

Amnesty was the Presidential Power to pardon that was exercised by Abraham Lincoln and Andrew Johnson. The amnesty was granted to those Southerners who pledge to be loyal towards the United States.

So, the correct answer is option D.

one of the major compromises in the constitutional convention was between the small states and big states. the small states wanted each state to have the same number of representatives in congress. the big states wanted representation based on population.
