Final answer:
Ida B. Wells is incorrectly matched with the cause of women's suffrage.
Step-by-step explanation:
The progressive reformer that is incorrectly matched with their cause is C) Ida B. Wells - Women's Suffrage. While Ida B. Wells was a prominent African American journalist, suffragist, and civil rights activist, her main focus was on combating racial injustice, particularly in the form of lynching and segregation. She advocated for the rights of African Americans, but her primary cause was not women's suffrage.
