Managerial accounting differs from financial accounting in that managerial accounting A. is required by Generally Accepted Accounting Principles (GAAP). B. emphasizes data relevance over data objectivity. C. tends to report on the company as a whole rather than segments of the company. D. is used primarily by external decision makers.

The correct option is (b)

Explanation:

Managerial accounting is for internal purpose for the managers for decision making. It is not mandatory as per GAAP, unlike financial accounting. Transactions are recorded as per the understanding of managers and not as per specific standards,

Managerial accounting focuses on data being relevant and not necessarily objective. Since, it caters to internal users, it is customized as per their requirement. Financial accounting, on the other hand needs to be highly objective as it caters to a wider audience who need transparent and reliable financial information.

Therefore, managerial accounting focuses on data relevance over data objectivity.
