A material weakness is a deficiency in internal control over financial reporting that could result in a significant misstatement of an entity’s financial statements. A regulatory agency overseeing the bank would want to review the documents that relate to the bank’s internal control over financial reporting and its ability to recover from the database failure. Based on the options given, the most relevant document for the regulatory agency to review is the Business Continuity Plan (BCP), which is a document that outlines how a business will continue operating during an unplanned disruption in service. The BCP would show how the bank prepared for and responded to the database failure, and what steps it took to restore normal operations and prevent further delays in financial deposits. The other documents are less relevant for the regulatory agency’s purpose, as they do not directly address the internal control over financial reporting or the recovery from the database failure. Therefore, the correct answer is A. Business Continuity Plan (BCP).
