Correct Answer: Both assertion and reason are correct, and the reason is not the correct explanation of the assertion.

Solution : The correct answer is (e) Both assertion and reason are correct, and the reason is not the correct explanation of the assertion.

The assertion that "The primary function of middle-level management is to develop long-term strategies and policies" is correct to some extent. Middle-level managers do play a role in developing and implementing strategies, but their primary function often involves more immediate coordination and execution of departmental activities.

The reason provided, "They are responsible for coordinating the activities of various departments," is also correct, but it doesn't fully explain the assertion. Coordination of departmental activities is a significant responsibility of middle-level management, but it's not the same as developing long-term strategies and policies, which often falls more into the realm of top-level management.
