Mrs. Higgins's point of view, as portrayed in this excerpt from "Pygmalion" by George Bernard Shaw, is influenced by the time and culture in which she lives. The most fitting description is option 2: "She cannot imagine a way for a woman to survive on her own."
The passage doesn't explicitly provide information about Mrs. Higgins putting her fingers in her ears, disapproving of boys playing with dolls, or being shocked by women enjoying cultural events.
In the excerpt, Mrs. Higgins seems to be critical or surprised by the idea of Eliza, a woman, being transformed through the efforts of the men (Higgins and Pickering). The notion of changing a woman into a "quite different human being" through altering her speech suggests a certain skepticism or disbelief in the agency and capabilities of women in that cultural context. Mrs. Higgins may find it difficult to envision a woman independently navigating and surviving in a world without significant intervention or guidance from men.
