Answer:
D. He is influenced by Charles, who sits next to him.
Step-by-step explanation:
The reason behind Laurie's misbehavior at school is that he is influenced by Charles, who sits beside him in school as there is much synonymity in Charles' behavior at school and Laurie's behavior at home like Charles hit the children, disobeys the guidelines of the teacher, similarly, Laurie spills his sister's milk, talks back, etc. Their parents fail to relate to the true reason for Laurie's misbehavior. Laurie misbehaves to seek consideration. Thus, option D is the answer.
