Final answer:
The Southern Alliance wanted to elect Senators directly by the people. Option B is correct.
Step-by-step explanation:
The Southern Alliance wanted to B) Elect Senators directly by the people.
Before the passage of the 17th Amendment in 1913, Senators were appointed by state legislatures. However, the Southern Alliance, along with other advocates for democratic reforms, pushed for Senators to be directly elected by the people, just like representatives in the House of Representatives.
This change occurred due to a series of scandalous elections in the late 1800s and early 1900s, which led citizens to resent Senators who they believed were selected because of personal connections rather than qualifications.
