Internet and intranet comparison – UGC NET Question

Intranets are internal networks of organisations (like a university campus network) accessible only to authorised users, while the Internet links networks worldwide and is publicly reachable.

Option A:
This option correctly contrasts scope (local vs global) and access (restricted vs public), which is the key distinction.

Option B:
Intranets are typically much smaller; the Internet includes countless intranets and other networks.

Option C:
A global mobile network is not what “intranet” means and may or may not connect to the Internet.

Option D:
The Web is a service over the Internet; an intranet is a private network that may host internal web services but is not simply “the Web”.
