配置DHCP服务器IP地址池的地址为193.45.98.0/24，其中193.45.98.10至193.45.98.30用作静态地址分配，正确的配置语句是

A.ip dhcp excluded-address 193.45.98.10,193.45.98.30 network 193.45.98.0 255.255.255.0

B.ip dhcp excluded-address 193.45.98.10,193.45.98.30 network 193.45.98.0 /24

C.ip dhcp excluded-address 193.45.98.10 193.45.98.30 network 193.45.98.0 0.0.0.255

D.ip dhcp excluded-address 193.45.98.10 193.45.98.30 network 193.45.98.0 255.255.255.0
