question: Q:An 8-year-old girl is brought to the physician by her parents because they are concerned with her behavior. She has temper outbursts six or seven times per week, which last anywhere between 5 minutes to half an hour or until she becomes tired. According to her father, she screams at others and throws things in anger “when things don't go her way.” He says these outbursts started when she was 6 and a half years old and even between the outbursts, she is constantly irritable.

Physical examination shows no abnormalities. During the mental status examination, she is uncooperative and refuses to answer questions. What is the most likely diagnosis in this child?? 
  {'A': 'Pediatric bipolar disorder', 'B': 'Conduct disorder', 'C': 'Disruptive mood dysregulation disorder', 'D': 'Oppositional defiant disorder', 'E': 'Intermittent explosive disorder'},
