The correct answer is: Option C. To persuade readers that women deserve the right to vote.
The author begins their statement by introducing a man's point of view in a scenario where women are allowed to vote, and how that would alter their ego and social behaviour. This is done as a means to present a reason for men not to take a policy like that so lightly. The author then, with the final phrase "Let the majority rule", clearly invites the readers to have their voices heard about the matter, expecting these to be raised on favor of women.
