The correct option is A Women voters will not support lawmakers who do not support suffrage
While arguing for women's right to vote, Catt asserts that when the bill does come into existence- and it will, the party(s) that have been an obstruction in its way will not find any allies amongst the people who have worked for the bill to come into existence. The idea of the women's suffrage bill will not cease to exist, but the party/parties that do not support it might. In this context, the line "when the party or parties which have so delayed woman suffrage finally let it come, their sincerity will be doubted and their appeal to the new voters will be met with suspicion" most definitely means that women voters will not support party/ parties that have not supported their cause. A is the best answer. The other options are incorrect as they do not fit into the context.
