Answer:
Each state should decide whether to be a free or slave state.
Step-by-step explanation:
Stephen Arnold Douglass was a lawyer and a politician born on 23rd April 1813. He was selected for Presidentship in 1860 election against Abraham Lincoln.
Douglass has been vague in his view on slavery. The historians still debate whether he was in favor of slavery or in oppose of it. In his 'Freeport Doctrine' he proposed that each territory have it's rights whether to be a slave free state or a slave state regardless of U. S. Constitution.
So, the correct answer is option A.
