Which part outlines the rules governing corporate debt resolution?

The correct choice is based on the knowledge that Part 313 of the FDIC regulations specifically addresses the rules governing corporate debt resolution. This part outlines the procedures and standards for handling and resolving issues related to corporate debts, which is a crucial aspect of maintaining financial stability and integrity within the banking system. Understanding these regulations is essential for financial institutions as they navigate corporate bankruptcies, restructurings, and related financial matters.

The other parts mentioned, while they cover different topics related to banking and financial management, do not specifically focus on corporate debt resolution. For example, Part 310 deals with procedures concerning enforcement actions, Part 309 addresses the process of supervisory and enforcement actions under the Bank Holding Company Act, and Part 308 pertains to administrative practices related to the FDIC's functions. Each part has its distinct focus and is structured to manage specific aspects of banking regulations and operations.
