The question requires identification of the incorrect statement regarding levels of management. Let's assess each option:
(A) Operational (lower) level management does handle day-to-day operations, including safety norms and implementation. This is correct.
(B) Middle-level managers act as a bridge between top and operational levels. They indeed ensure departments are staffed adequately. This is correct.
(C) This is incorrect. The Chief Executive Officer (CEO), a top-level executive, is responsible for setting vision, direction, and broad strategic decisions, not the direct activities of first-line managers. Direct supervision of operational tasks is the responsibility of middle and lower-level managers, not top-level executives.
(D) Top-level managers are indeed accountable for overall functioning of the business and societal impact. This is correct.
Hence, statement (C) wrongly attributes lower-level managerial responsibilities to the CEO and is therefore the incorrect one.
Final Answer: (C) Chief Executive officer at Top Level management is responsible for all activities of first line managers.
