Answer:
The narrator feels inadequate when she reports seeing a supernatural being and nobody believes her is the correct answer.
Step-by-step explanation:
The Lady Maid's Bell was written by Edith Wharton; this short story was first published in 1902. Hartley, a lady's maid, finds a job with Mrs. Brympton, who should stay in her country due to health problems. Hartley has a good time adapting to the house and mates, but the room opposite to hers is locked and nobody wants to hell Hartley about the pale woman.
Letter A is correct because there is a supernatural element that is not explained to the character, and even further, it is being hidden to her. The story occurs in a time when employees just did their job without asking anything about their predecessors; another indicator is that Agnes is very loyal and doesn't want to reveal nor admit that there is something wrong going on.
