请参见图示。R2 路由表如下：Gateway of last resort is not set 10.0.0.0/30 is subnetted, 2 subnets C 10.0.0.0 is directly connected, Serial0/0/0 C 10.0.0.4 is directly connected, Serial0/0/1 192.168.10.0/26 is subnetted, 3 subnets S 192.168.10.0 is directly connected, Serial0/0/0 C 192.168.10.64 is directly connected, FastEthernet0/0 S 192.168.10.128 [1/0] via 10.0.0.6 路由器R2用19216.81.129的数据包做什么？
选项：

A:丢弃数据包;
B:将数据包发送到接口 Serial0/0/0;
C:将数据包发送到接口 Serial0/0/1;
