Your customer wants to monitor the balances of their key General Ledger (GL) accounts on a regular basis and asks your advice on the best reporting option. Which reporting tool would you suggest?

Account Groups are used to group key General Ledger accounts for monitoring and analysis. The Sunburst visualization tool, available in the Financial Reporting Center, provides an interactive, graphical representation of the balances in these account groups. This combination is specifically designed for at-a-glance, regular monitoring of key account balances, making it the most suitable option for the customer's requirement. It allows users to drill down from a summary view to detailed balances, offering a powerful yet intuitive user experience for tracking financial performance.

B. Financial Reporting Studio is primarily for creating highly formatted, statutory reports like balance sheets and income statements, not for interactive, regular monitoring of a subset of accounts.
C. Smart View is an Excel add-in for ad-hoc analysis, querying, and data submission. While powerful, it is not the primary tool for simple, visual, and regular balance monitoring.
D. Oracle Transactional Business Intelligence (OTBI) is a broad ad-hoc reporting tool for real-time transactional data, but Account Groups and Sunburst are purpose-built for this specific GL monitoring task.
