Explanation:

The sentence in the Dred Scott v. John F.A. Sandford case of March 6, 1857, is one of the most infamous sentences of the US Supreme Court. The judges (7-2) argued that African Americans were not American citizens and then could not sue other people in court; that the 1820 Missouri Compromise that had declared free of slavery all states west of Missouri and north of latitute 36°30′, was unconstitutional; and that slave Dred Scott could not  recover his freedom just because he had lived in a free state before. It is considered the worst sentence in judicial American history.

the answer is c. many americans held nativist or racist views

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
