What happened to Lily at her father's house?

• A. Her stepbrother touched her under her bra
• B. Her father locked her in her room
• C. Her father was concerned about bruises
• D. Nothing happened

Answer: (A)

This item hinges on recognizing sexual abuse by a family member. Describing Lily being touched under her bra by her stepbrother is a clear boundary violation of a minor and a form of maltreatment that must be reported and acted upon to keep her safe. In real practice, this kind of information triggers mandatory reporting to child protective services or the appropriate authorities, and steps should be taken to protect Lily while the case is investigated.

The other described situations don’t fit this specific abusive act: being locked in a room points to confinement or neglect, a parent expressing concern about bruises might indicate concern but doesn’t itself describe the abuse, and nothing happened contradicts the scenario given. The key idea is that the explicit sexual interaction by a family member constitutes abuse that requires protective action.
