The statement "A business has one type of management responsible for the management of a more or less specialised group of activities" is incorrect.

Businesses typically have various levels and types of management, each responsible for different specialized functions or groups of activities. For example, there are top-level managers (strategic planning), middle-level managers (departmental oversight), and lower-level managers (day-to-day operations). Additionally, management can be specialized by function, such as financial management, marketing management, human resources management, and operations management. Each of these manages a specific, specialized group of activities.
