The most accurate answer among the choices is the second one, because the main goal of the conservatives during the 1800's was to restore power to the monarchs, and go back to the old ways. Hope my answer has come to your help.
Answer: A monarch made key political decisions based on input from advisors.
During the 1800s, most of Europe was still governed by monarchs. However, the republican, democratic example of the United States was heavily influential in liberal circles. Conservatives at that time period wanted to protect the institution of monarchy. So out of the options, it is more likely that conservatives would have supported keeping the monarch, while receiving input from advisors.
