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. Two equal-cost default routes are formed on RTB.

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

D. RTB prefers RTA to access the Internet because the path to RTA is shorter.
