Which is the best evidence for a claim supporting mandatory school uniforms? a recent study concluded school uniforms improve graduation and attendance rates. school uniforms violate a student's right to freedom of expression. school uniforms might possibly diminish social barriers between students. school uniforms can be a financial burden for some families?

The correct answer is: school uniforms might possibly diminish social barriers between students.

School uniforms provide a set standard on what students should be wearing on a regular basis in schools. It diminishes social barriers between students because the standard only requires a singular and adhesive attire that everyone is required to wear. Branded items and clothes will no longer be a social status quo that would be prominent in school environments.
