ZXUN-xGW GGSN新增动态地址池后会自动生成ACL。由于全局ACL条目有限制，需要合理规划地址池。下列地址段配置生成ACL最少的是（）

A.segment 10.123.1.010.123.1.255mask 255.255.255.0cpulocation 2/1
B.segment 10.123.1.110.123.1.254mask 255.255.255.0cpulocation 2/1
C.segment 10.123.1.110.123.1.255mask 255.255.255.0cpulocation 2/1
D.segment 10.123.1.210.123.1.255mask 255.255.255.0cpulocation 2/1
