In the context of computer networks, which of the following best describes the transmission of a message using packet switching?

In packet switching a message is split into packets that may travel by different routes and arrive at different times and out of order.

The claim that packets always follow the same route and arrive together in order describes circuit switching, not packet switching.

The claim that packets follow one fixed route yet arrive at varied times is internally inconsistent for packet switching.

The claim that packets take different routes but always arrive together in order contradicts how variable routing works.

The receiving device reassembles the packets into the original message using sequence numbers.

Packet switching makes efficient use of shared network links, as the internet does.
