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

The assertion states that the principle of "Scalar Chain" facilitates effective communication and coordination. This is true because the scalar chain in an organizational hierarchy provides a clear path for communication and coordination, helping to streamline the flow of information and decision-making.

The reason provided is that it ensures information flows through the chain of command without distortion. This is also true. The scalar chain helps in maintaining the integrity and accuracy of information as it passes through the levels of the organizational hierarchy. The chain of command ensures that information is transmitted without being significantly altered or distorted as it moves from higher levels to lower levels and vice versa, aiding effective communication and coordination. Therefore, the reason correctly explains why the assertion is true.
