Refer to the exhibit. A network engineer is implementing an OSPF configuration. Based on the output, which statement is true?

OSPFv3 does not run for IPv4 on FastEthernet0/0 until IPv6 routing is enabled on the router and IPv6 is enabled on interface FastEthernet0/0.
In the ospfv3 1 area 1 ipv4 command, area 0 must be configured instead of area 1.
OSPFv3 cannot be configured for IPv4; OSPFv3 works only for IPv6.
“IPv6 routing not enabled” is just an informational message and OSPFv3 runs for IPv4 on interface FastEthernet0/0 anyway.
