The correct answer is A. Odyssean journey
This is an allusion to the great Greek epic Odyssey, and requires people to know what happens in the Odyssey to understand.
I would say that a character who is a stereotype has an over the top, exaggerated personality.
very concerned about appearance
The excerpt describes the grandmother's appearance. She is described as having white gloves, a navy blue dress trimmed with lace, and a sailor hat with a bunch of violets. She is compared to the mother to show that her way of dressing is different than what is required of her visit because the mother is dressed in slacks and has her hair up in a kerchief. It goes on to say that the grandmother would be easily identified as a lady if she was found on the side of the road. This label of being a lady seems to be important and only communicated through appearance.
