Explanation:

The correct answer is to inquire about the possibility of sexual abuse. Injuries to the soft palate such as bruising, abrasions, and petechiae can be signs of sexual abuse in infants. While oral sex may not leave significant physical evidence, these findings should raise suspicion. Option A is correct as it focuses on addressing potential abuse. Options B, C, and D are incorrect because the child's diet, the type of bottle used for feedings, and play objects are not likely related to the observed injuries. The presence of oral injuries suggests considering sexual abuse rather than other factors.
