Final answer:
The correct answer is option b) The first presidential election where women from all states could vote.
Step-by-step explanation:
The significant change that occurred during the 1920 presidential election is b) The first presidential election where women from all states could vote. This landmark event came after the ratification of the 19th Amendment in August 1920, which granted women the right to vote.
Following the suffrage movement's hard-fought battle and strategic political lobbying, this amendment marked a pivotal shift in American electoral politics. The 1920 election saw Republican Warren Harding rising to the presidency, with a campaign that was noted for its call for a "return to normalcy" following the Progressive era and Woodrow Wilson's tenure.
