Internet data, whether in the form of a Web page, a downloaded file or an e-mail message, travels over a system known as a packet-switching network. In this system, the data in a message or file is broken up into packages about 1,500 bytes long. Each of these packages gets a wrapper that includes information on the sender's address, the receiver's address, the package's place in the entire message, and how the receiving computer can be sure that the package arrived intact. Each data package, called a packet, is then sent off to its destination via the best available route -- a route that might be taken by all the other packets in the message or by none of the other packets in the message.

According to the text, which description below of the transmission process is NOT true?

A) The receiving computer can determine whether or not the package is intact all by itself.

B) In a packet-switching network, the data cannot be transmitted without being cut into packages.

C) Apart from the data, a package also carries with it some other information.

D) There are different routes for the transmission of data in a packet-switching network.
