The correct answer can be A, Because that student knows that cutting her self she will bleed and maybe loose a lot of blood. Its not B , because they didn't plan it. Its not C , because it was an accident.
Intentional injuries include interpersonal violence (homicide, sexual assault, neglect and abandonment, and other maltreatment), suicide, and collective violence (war). A student herself decides to cut herself so it is not an accident it was intentionally so it will be intentional injury
