The next hops are learned via OSPF and IS-IS. Which path is selected as the best path for
10.168.0.1?

A.
the path via 10.0.0.2, because it is an MPLS labeled path

B.
the path via 10.0.0.2, because the next hop is learned via OSPF with an AD of 110, compared
to 115 for IS-IS

C.
the path via 10.0.0.3, because it has the highest router ID

D.
the path via 10.0.0.3, because it has the lowest IGP metric

Explanation:
10.0.0.3 has the lowest IGP metric therefore, it will be selected as the best path for 10.168.0.1.
