The correct answer is c. could be banned in a territory only by a vote of the people.

To determine the correct answer, we need to understand the concept of popular sovereignty and its relation to slavery. Popular sovereignty refers to the idea that the power of the government is derived from the consent of the people. In the context of slavery, popular sovereignty played a significant role in the debate over whether slavery should be allowed in new territories and states during the mid-19th century in the United States.

Popular sovereignty allowed the people of a particular territory or state to decide whether or not to allow slavery. This means that the fate of slavery in a particular area was determined by the majority vote of the people living there. So, the correct answer is:

c. could be banned in a territory only by a vote of the people.

According to popular sovereignty, the people in a territory had the authority to decide if they wanted to allow or ban slavery. This concept was put into practice through various legislative measures such as the Missouri Compromise and the Kansas-Nebraska Act, where the residents of those territories were empowered to choose whether to permit or prohibit slavery through a democratic process.
