Final answer:
Option (c), Percy's mother sends him to camp alone due to danger, signaling his growth and independence as part of his character development in the story.
Step-by-step explanation:
Percy's mother advises him to go to the camp alone primarily because it is too dangerous for her, not because she desires alone time, lacks love for her son, or is overprotective. This situation depicts a common theme in literature where a young protagonist must embark on a journey or quest independently, facing challenges that spur growth and development.
Percy's journey to the camp alone is a pivotal moment that propels him into the adventure that lies ahead, shaping his character and destiny.
