Which outcome best replaces the question mark in this sequence chain?

Explanation

Dred Scott was an African-American born in the United States who became popular in 1857 for demand his freedom and his family, arguing that they should be granted freedom because they had lived in Illinois and Wisconsin for four years, where slavery was illegal. However, the United States Supreme Court did not agree to his demand considering that African Americans could not claim citizenship in the United States and consequently could not establish a claim in federal court. Later, in 1863, President Abraham Lincoln made the Emancipation Proclamation in which he established the status of African Americans as free slaves. Based on the foregoing, it can be inferred that the Emancipation Proclamation was a subsequent event to the Supreme Court's refusal of Dred Scott's claim. So the correct answer is B.
