The caregiver brings his 23-month-old son for a well-child check. The caregiver apologizes for his own sniffling, saying he has allergies. He reports that the toddler seems slower to progress than his older children did.
 
  The nurse notices that although the child sits in the caregiver's lap without fear or hesitation and responds to the caregiver's questions, the child never looks at the caregiver's face when the caregiver speaks to him. The family situation should be further investigated because the child's behavior might be indicative of a:
  A) child who is autistic.
  B) child who has attention deficit hyperactive disorder.
  C) a caregiver who is abusing the child.
  D) a caregiver who is addicted to cocaine.
