The correct answer is "Internet" because it is the only option that can cover a whole country. LAN (Local Area Network) is limited to a small area like a building or a campus. MAN (Metropolitan Area Network) covers a larger area like a city. WAN (Wide Area Network) covers a wider geographical area, but it may not necessarily cover an entire country. Only the Internet has the capability to connect networks globally, making it the correct answer.

The given answer is incorrect. The benefits of computer networks mentioned in the question include sharing resources, using data together, and having higher reliability. However, accessing someone else's data without being noticed is not a legitimate benefit of computer networks. It goes against ethical and legal principles of privacy and data security.
