Router R1 has a connected route for 10.1.1.0/24 off interface Fa0/0. Interface Fa0/0 has been enabled for OSPF due to a router ospf 1 and network 10.0.0.0 0.0.0.255 area 0 command. R1 also has EIGRP configured, with the redistribute ospf 1 metric 1000 100 10 1 1500 command configured under EIGRP.
Which one of the following is true?（）
A. R1 will not redistribute 10.1.1.0/24 into EIGRP, because R1 knows it as a connected route and not as an OSPF route.
B. For any OS PF routes redistributed into EIGRP, the metric components includea value equivalent to 1 Mbps of bandwidth.
C. For any OSPF routes redistributed into EIGRP, the metric components include a value equivalent to 100 microseconds of delay.
D. No subnets of network 10.0.0.0 will be redistributed due to the omission of the subnets parameter.
