A router has learned three possible routes that could be used to reach a destination network One route is from EIGRP and has a composite metric of 07104371.
Another route is from OSPF with a metric of 782 The last is from RIPv2 and has a metric of 4 Which route or routes will the router install in the routing table?
A. the EIGRP route
B. the OSPF route
C. the RIPv2 route
D. all three routes
E. the OSPF and RIPv2 routes
It’s the administative distance that is relevant here:
EIGRP = 90
OSPF = 110
RIP = 120
The route with the lowest metric is placed in the routing table.

As you can see from the output, only D (EIGRP) routes are in the routing table hence A is correct.
I dont think you can compare metrics of different protocols like that. Answer is D!
Answer is A. The route with Admin Dist 90 is going to routing table
