Solution : The correct answer is (a) Both assertions and reasons are correct, and the reason is the correct explanation of the assertion.

The assertion that the principle of "Unity of Command" avoids conflicts and confusion in an organization is correct. Unity of Command is a management principle that suggests that an employee should have one and only one supervisor to report to, which can help in preventing conflicting instructions and reducing confusion regarding responsibilities and tasks.

The reason provided, stating that it ensures each employee reports to only one supervisor, is also correct. This principle indeed mandates a clear reporting structure where each employee has a single direct supervisor, helping in maintaining a clear line of authority and minimizing conflicting directions.
