According to a different source, these are the options that come with this question:
a. the nursery: women being treated like children
b. the pattern of the wallpaper: freedom
c. yellow: sickness
d. the house: isolation
The association between the pattern of the wallpaper and the concept of freedom does not exist in this text. In fact, the association is the opposite one. The pattern of the wallpaper is described as similar to bars, like the ones that would exist in a prison cell. The pattern of the wallpaper is intended to symbolize the imprisonment that the woman suffers.
