The federal child abuse prevention and treatment act (capta; 42 u. s.c. a. § 5106g) makes it mandatory for parents, guardians, and professionals dealing with children to all acts of child abuse they encounter.

I would assume that the correct answer will be - The Federal Child Abuse Prevention Treatment Act makes it mandatory for parents, guardians, and professionals dealing with children to report all acts of child abuse they encounter. That would make the most sense to me as all acts of child abuse should be reported to the appropriate authorities.
