Answer:
A) Legal protection for slavery was stregnthened.
Step-by-step explanation:
The Scott vs. Sandford case was one in which Dred Scott, a slave, sued for his freedom. Scott sued for his freedom because his owner brought him to live in a territory that outlawed this institution. Scott believed that living in a free territory made him free.
However, the Supreme Court ruled against Scott and stated that slaves are not people. Rather, they are property. This means they have no legal rights. This ruling allowed slavery to exist in any part of the US, making the institution of slavery stronger within the US.
