Correct option is A
In order to challenge prevalent stereotypes among students, it is important to present examples that do not conform to those stereotypes. This approach helps in breaking down preconceived notions and biases by providing alternative narratives and perspectives. By exposing students to diverse and counter-stereotypical examples, educators can encourage critical thinking and foster a more inclusive and understanding mindset. This method contrasts with reinforcing stereotypes through biased materials (option b), considering only the dominant group's viewpoint (option c), or avoiding discussions on diversity and individual differences (option d), all of which would perpetuate stereotypes rather than challenge them.
