The traits of a hero are determined by

A. cultural values.
B. their experiences. <-- this is my answer
C. the plot of the story.
D. their mentors.

The traits of a hero can be influenced by several factors, including cultural values, their experiences, the plot of the story, and their mentors. However, if we are looking to determine the primary factor that determines the traits of a hero, it is usually their experiences, or in other words, option B.

Experiences play a crucial role in shaping a person's character and defining their traits. Heroes often undergo different challenges, trials, and hardships throughout their journey, which ultimately shape their beliefs, values, and actions. These experiences can be physical, emotional, or psychological, and they help heroes develop qualities like courage, resilience, determination, empathy, and selflessness.

By facing and overcoming obstacles, heroes learn from their experiences and grow, which shapes their traits. They may learn valuable lessons, gain new skills, or develop a stronger sense of justice and morality. These experiences can be influenced by cultural values, the plot of the story, or the guidance of mentors, but ultimately it is the individual hero's response and growth through their experiences that define their traits.

So, while cultural values, the plot, and mentors can have an impact on the traits of a hero, it is the experiences that heroes go through that primarily shape their character and determine their traits.
