The show interfaces serial 0/0 command was issued on the router.
Based on the output displayed which statement is correct?

A. The cable connected to the serial 0/0 interface of the MIK router is a DTE cable.
B. The MIK router can ping the router interface connected to the serial 0/0 interface.
C. The clock rate used for interface serial 0/0 of the MIK router is 1544000 bits per second.
D. The CSU used with the serial 0/0 interface of the MIK router has lost connection to the service provider.
E. The interface of the remote router connected to the serial 0/0 interface of the MIK router is using the default serial interface encapsulation.

HDLC is the default encapsulation type for the serial interfaces for the Cisco routers
