Final answer:
Option D, 'managing the physical information system of the firm,' is not a part of the accounting function which focuses on financial data and managing transactions.
Step-by-step explanation:
The question asks which of the following options is not part of the accounting function. The correct answer is option D: managing the physical information system of the firm. The accounting function primarily deals with managing the firm’s financial information resources, capturing and recording transactions in the database, and distributing transaction information to operations personnel. However, managing the physical information system, which might include hardware and software maintenance, is typically a task for the IT department rather than accounting. The accounting department focuses on financial data and transactional processes, ensuring accuracy and compliance with financial regulations.
