Answer:
C. that both groups were viewed as being naturally incapable and thus unfit for suffrage.
Step-by-step explanation:
During the early 19th century, the right to vote was a privilege of only the white men, even excluding their womenfolk. Voting and having any say in the political sphere was an advantage that was allowed only to the male whites. This was because women and the colored people were not deemed fit to be able to make decisions or be involved in the welfare of politics.
But as the years passed and the idea of democracy became more and more developed, the women were also deemed fit to be part of the suffrage system, though it was also a result of almost a decade of protest against the discrimination of women. Towards the late 19th century, the right to allow blacks to vote also began to emerge. And women's suffrage was officially achieved into being by the 1920s.
