By default, how does EIGRP determine the metric of a route for the routing table?

A. It uses the bandwidth and delay values of the path to calculate the route metric. B. It uses a default metric of 10 for all routes that are learned by the router. C. It counts the number of hops between the receiving and destination routers and uses that value as the metric. D. It uses a reference bandwidth and the actual bandwidth of the connected link to calculate the route metric.
