The correct answer is b) Controller.
The role of a Chief Accounting Officer (CAO) in a company is primarily focused on overseeing the accounting department and ensuring accurate financial reporting and compliance with regulations. The title ‘Controller’ is widely used to describe this position, as controllers are responsible for managing the financial controls and ensuring the integrity of the company’s financial statements.
While the other options such as president, treasurer, and vice president may relate to financial oversight or broader management roles, they typically do not specifically denote the chief accounting responsibilities associated with the title of Controller.
