Answer:
B. When students wear their own clothes to school, unkind comparisons hurt students.
Step-by-step explanation:
If you are wanting to convince schools to require uniforms, you might as well tell them some reasons why it is better than letting students wear their own clothes. By writing that students can be made fun of wearing their own clothes, you are supporting the fact that it is better to require school uniforms so that students will not be judged by what they wear.
