Мальчик действительно расстроился потому что:
1.Ему не нравится его школьная униформа.
2.Учитель назвал его хулиганом и преступником.
3.Он не чувствует себя удобно в школьной форме.

Answer 2

Among the options provided, it seems that option b is the most likely cause for the boy feeling upset. Being called a "hooligan" and a "criminal" by a teacher would likely have a significant negative impact on the boy's emotions and self-esteem, leading to him feeling really upset. The other options (a and c) are related to the school uniform and comfort, but being accused of serious misconduct by a teacher would likely have a stronger emotional impact.
