When OSPF learns multiple paths to a network, how does it select a route?

It multiple the active K value by 256 to calculate the route with the lowest metric.

For each existing interface, it adds the metric from the source router to the destination to calculate the route with the lowest bandwidth.

It divides a reference bandwidth of 100 Mbps by the actual bandwidth of the existing interface to calculate the router with the lowest cost.

It count the number of hops between the source router and the destination to determine the router with the lowest metric
