Explanation:
Gilman’s most likely reason for sending a copy of her story “The Yellow Wallpaper” to her former physician was to challenge his medical treatment of her and other women suffering from mental illness. The story was based on her own experiences of being diagnosed with hysteria and treated with the “rest cure,” which involved being confined to a room and prohibited from any intellectual or creative stimulation. By sending the story to her physician, Gilman was highlighting the harmful and oppressive nature of this treatment and advocating for a more humane approach to mental health.
