R1 is currently advertising prefixes 1.0.0.0/8, 2.0.0.0/8, and 3.0.0.0/8 over its eBGP connection to neighbor 2.2.2.2 (R2). An engineer configures a prefix list (fred) on R1 that permits only 2.0.0.0/8 and then enables the filter with the neighbor R2 prefix- list fred out command. Upon exiting configuration mode, the engineer uses some show commands on R1, but no other commands.Which of the following is true in this case?（）

A. The show ip bgp neighbor 2 .2.2.2 received -routes command lists the three original prefixes.

B. The show ip bgp neighbor 2.2.2.2 advertised - routes command lists the three original prefixes.

C. The show ip bgp neighbor 2.2.2.2 routes command lists the three original prefixes.

D. T he show ip bgp neighbor 2.2.2.2 routes command lists only 2.0.0.0/8.
