Step 1: Understanding the role of a manager. 
  
In management, a manager's role goes beyond being just a boss. A manager must lead their team, motivate employees, and provide direction. Leadership, rather than authoritarian management, is essential for motivating and guiding the workforce. 
Step 2: Analyzing the options. 
  
(A) Boss: This is a limited view of the manager's role. While a manager may give orders, their primary role is to lead the team. 
  
(B) Owner: This is incorrect. The manager is not necessarily the owner of the business or company. 
  
(C) Leader: Correct. A manager is primarily a leader who guides and motivates the team. 
  
(D) None of these: This is incorrect because (C) is correct. 
Step 3: Conclusion. 
  
The correct answer is (C) Leader, as a manager's primary role is to lead the team effectively.
