Answer: a. Mandatory reporters work frequently and closely with children.
Step-by-step explanation:
Mandatory reporters are people who are required by law to report either known or suspected instances where children might have been abused or neglected.
These people are mandated by law to do so because it is assumed that their profession allows them to work closely and frequently with children and so they will have ample opportunity to see if a child is being neglected or abused.
Such careers include: dentists, psychologists, physicians and many more.
