Answer:
b. argued that the vote would enable women to extend their roles as mothers and homemakers to the public world.
Step-by-step explanation:
Defenders of women's suffrage sought liberation and the social valorization of women through the vote. For these people, once women could vote, they would have political representation that would fight for their rights, and allow them to have protection and social freedom. This would extend the roles that women were subjected to, allowing them to be more than just mothers and housewives and to decide and control their lives independently.
