Comprehensive and Detailed In-Depth Explanation:
An intranet is a private network used by an organization for internal communication and information sharing among employees. It is accessible only to authorized personnel within the company.
Option A (Extranet) – Allows external parties (e.g., suppliers, partners) to access limited information.
Option B (LAN) – Refers to a network infrastructure rather than controlled access.
Option D (Internet) – Is public and not restricted to internal personnel.
