The correct answer is: 2) The internet

Explanation:
A Wide Area Network (WAN) is a type of network that spans a large geographical area, often a country or even the globe, and connects multiple smaller networks like LANs and MANs.

Options Analysis
1) A home Wi-Fi network → This is a Local Area Network (LAN), limited to a small area like a house.

3) A Bluetooth connection → This is a Personal Area Network (PAN), with a very short range.

4) A local office network → Again, this is a LAN, restricted to an office building or floor.
