   Broadband is used for high speed Internet connections at a fixed monthly rate. It turns an exciting telephone line into a high speed digital line capable of carrying data up to 40 times conventional modem speeds.
   For home owners and families there are many advantages. One of the most important is simultaneous access to both telephone lines and the Internet. For businesses, broadband can improve customer relations and provide direct access to corporate e-mails and databases. Entire operations can go online.  
Compared with the modem speed the broadband technology can transmit data_______.
选项 A、at up to forty times of ordinary speed
B、much more faster
C、at a high speed
D、within a second
