The correct response is:
Ona finds a bungalow that is falling apart but feels safer there than where she was before.
This central idea is conveyed through the imagery that illustrates both the conditions of the bungalow and Ona's feelings about finding shelter there as she seeks safety on higher ground. The description of the missing walls and the birch tree suggests deterioration, yet her decision to settle there indicates a sense of safety compared to her previous circumstances.
