What is the role of the Attorney General during an investigation?

The correct response highlights the function of the Attorney General in legal investigations, which includes the authority to subpoena documents that are pertinent to the investigation. This ability to issue subpoenas is essential for gathering evidence and obtaining necessary information that may be crucial for understanding the facts of a case or for enforcing the law. By compelling individuals or organizations to provide documentation or testimony, the Attorney General can ensure that investigations are thorough and based on comprehensive information.

The other options do not accurately reflect the primary responsibilities of the Attorney General in an investigative capacity. Providing legal representation to brokers does not fall under the purview of the Attorney General, as their role is more focused on representing the state’s interests and upholding the law rather than acting as counsel for private entities. Defining ethical practices for brokers would be more aligned with regulatory agencies rather than the Attorney General's direct responsibilities. Lastly, while mediation services can be important in disputes, this is not a typical function of the Attorney General during an investigation, which is more focused on legal proceedings and enforcement.
