Final answer:
Option (C), New Jersey was the only state in the New England and Mid-Atlantic regions to offer partial women's suffrage before 1920, granting the vote to single women who were property owners.
Step-by-step explanation:
The question asks which New England and Mid-Atlantic states had partial women’s suffrage before 1920. Based on historical records, New Jersey was the only state in these regions to grant a form of women's suffrage before 1920. New Jersey allowed single women who owned property to vote until this right was rescinded in 1807.
While in 1917, New York became the first East Coast state to approve women's suffrage, it was not partial, but full suffrage. Therefore, the correct answer is New Jersey and Rhode Island, which corresponds with option C.
