The correct choice is: Both use a third-person limited point of view.
In both "The Open Window" by H. H. Munro (Saki) and "A Cup of Tea" by Katherine Mansfield, the narrators provide insight into the thoughts and feelings of specific characters without fully revealing the thoughts of all characters involved. They focus on the perspectives of Framton Nuttel in the first text and Rosemary in the second text, respectively, which exemplifies the third-person limited point of view.
