Which case clue shows that a question is about the professional nature of management?

Correct answer: Mention of specialised knowledge, ethics, service motive and professional association.

The governing concept is recognition of the characteristic features of a profession. Option A is correct because specialised knowledge, ethical standards, a service motive and professional associations are all standard clues used to discuss management as a profession. In a case-based question, these terms direct the learner to examine whether management fulfils professional requirements and where it falls short, such as the absence of compulsory licensing for every manager. Option B may relate to production or operations, but quantity alone does not identify professional nature. Options C and D are merely descriptive details with no necessary connection to professional status. Therefore, A provides the strongest and most relevant clue.
