As shown in the figure, RTB, RTC and RTA establish IBGP peers, and RTA is the reflector of RTB and RTC. Currently RTA and RTC are egress routers connecting to the Internet. In order to make RTB access the Internet through RTA or RTC, a default route is configured on RTA and RTC, and advertised using the network command.
Which of the following statements is correct is _____.

A. If RTB prefers RTC to access the Internet, it is necessary to establish a peer relationship between RTB and RTC and set relevant routing attributes.

B. RTB prefers RTC to access the Internet. Only when the export of RTB is interrupted, can RTB access the Internet via RTA

C. RTB prefers RTA and RTC, depending on the attributes of the default routes advertised by RTA and RTC

D. RTB prefers RTA to access the Internet. Only when the export of RTA is interrupted, can RTB access the Internet via RTC
