Final answer:
In New Jersey, mandatory reporters of child abuse include educators, medical professionals, law enforcement, social workers, school administrators, and daycare providers.
Step-by-step explanation:
According to NJ state law, the groups considered to be "mandatory reporters" of child abuse include educators, medical professionals, and law enforcement, which corresponds to option (a). Mandatory reporters are individuals who, because of their profession, are legally required to report any suspicion of child abuse or neglect to the appropriate authorities. In New Jersey, this responsibility extends to social workers, school administrators, and daycare providers as well, indicating a broad approach to protecting children through the vigilance of those in positions of authority and trust.
