Final answer:
The option that is not characteristic of managerial accounting information is 'b. Emphasizes the external financial statements' as managerial accounting focuses on internal management needs rather than external reporting.
Step-by-step explanation:
The characteristic of managerial accounting information that is not accurate is b. Emphasizes the external financial statements. Managerial accounting tends to focus more on providing information for internal management within a company rather than external parties. It provides detailed information on various parts of the company that is useful for decision-making, emphasizes relevance, and has a forward-looking focus, which are all aspects that serve the internal management's needs for planning, directing, and controlling a company's operations.
On the other hand, financial accounting is the field that deals with the preparation of external financial statements that summarily report the financial performance and position of a company to outside stakeholders such as shareholders, creditors, and regulatory agencies.
