In which of the following excerpts from "the yellow wall paper" does author charlotte perkins gilman seem to mock the romantic belief in the supernatural? a. a colonial mansion, a hereditary estate, i would say a haunted house, and reach the height of romantic felicity—but that would be asking too much of fate! b. there is a delicious garden! i never saw such a garden—large and shady, full of box-bordered paths, and lined with long grape-covered arbors with seats under them.c. the color is repellent, almost revolting; a smoldering unclean yellow, strangely faded by the slow-turning sunlight.d. then i peeled off all the paper i could reach standing on the floor. it sticks horribly and the pattern just enjoys it!
