Which action indicates that an arrest was made for child abuse?

The choice indicating that an arrest was made for child abuse is correct because it directly references the legal action taken against an individual in relation to a child abuse case. When a person is arrested for child abuse, it signifies that law enforcement has substantiated evidence or reasonable cause to believe that abuse has occurred, leading to that individual's detention. This action is a formal step in the criminal justice process, where a suspect is taken into custody based on allegations of harming a child.

In contrast, the other options reflect actions that may be part of the broader investigation or welfare system but do not imply that an arrest has occurred. A welfare check typically ensures a child's safety without necessarily leading to an arrest. An investigation of neglect might indicate concerns about a child's wellbeing but does not confirm criminal charges. Conducting a parent-guardian interview is often a means of gathering information to assess the situation, but it does not itself constitute an arrest. Thus, the correct answer specifically denotes the legal measure of arrest in relation to child abuse.
