Explanation:
Stakeholders include all parties, both internal (e.g., employees, management) and external (e.g., suppliers, government, community), who have a direct or indirect interest in the organisation’s activities. Option A limits stakeholders to shareholders, which is too narrow. Option B restricts it to equity and debt investors, also incomplete. Option D excludes external stakeholders. Option C encompasses the broadest and most accurate definition, making it the correct answer.
