Which of the following is a tactful response to give when a student misbehaves?

I would say C: "I don't like it when you do that." because this clearly conveys the teacher's dislike with the student's behavior without berating them. A: "Stop being bad!" may have the opposite effect on a child and they may continue doing it just to irk the teacher further. B: "Now look what you've done!" may give the child a sense of accomplishment at making the teacher angry. D: "Sometimes you're terrible." berates the child and insults them rudely. They may continue doing bad things just to infuriate the teacher as a result of that mean comment.

C. " I don't like it when you do that"
I said c because tactful means sensitive or nice and c is the only sensitive way to tell a child about there behavior

Physical stimulation can not be used as you carnt ask 1/2 a person a it would be painful
