The correct answer is A.
In the story, the death of her husband would make Louise a widow. This means that she would have no obligation to re-marry, and therefore she would not have to submit herself to another man. Only then she would be free to do as she pleases.
It is very important that the setting of the story is during the nineteenth century because during that time, women were very dependant on men. They were oppressed and forced to stay home to run the household.
