Why did the women's movement remain incomplete even after women received some social reforms?

Correct answer: Because full political suffrage and equality in public offices were not achieved

The governing concept is the distinction between social reform and political equality. Improvements in education, marriage arrangements or training could change women's social position, but they did not automatically give women the right to vote, stand for office or exercise equal public authority. Therefore option A is correct: the movement remained incomplete because full political citizenship and equality in offices were still denied. Option B is too absolute, since educational reform was discussed and pursued. Option C is also too absolute, and option D ignores the petitions, clubs, publications and campaigns through which women clearly expressed demands.
