Hello there,
The line from the story that reveals Montresor's true intentions would be option C: "I had finished a portion of the last and the eleventh; there remained but a single stone to be fitted and plastered in."
Hope this helps and have a great day :)
In “Walk Two Moons” by Sharon Creech, Sal’s mom left her but she didn’t believe that her mother would leave her and not come back. So Sal went on a road trip with her grandparents to search for her mother. She ended up traveling through many different place and came to find out that her mother had passed away in a bus crash a while ago. Sal passed by her mother’s grave as she was going back home, losing the hope that she had about finding her mother. All she was able to do was live passed it and continue living her life with the people she had.
