The correct answer is D. Suffragists who protested outside the White House
Explanation:
The "Silent Sentinels" were a group of women that protest by using silence outside the White House on January of 1917 to show President Woodrow Wilson they supported women suffrage and therefore were suffragist as Woodrow did not support this. The group of women led protests every week for two years until the Nineteenth Amendment was passed and this ratified women could vote as any citizen could be denied to vote on the basis of gender. But unfortunately, during this time of protests, multiple cases of abuse and unfair arrest occurred against women. Therefore, the "Silent Sentinels" were basically female suffragists who protested outside the White House to try to defend and ratify their right to vote.
