Why each option

This question asks for the routing table entry component that defines the subnet mask.

Arouting protocol code

The 'routing protocol code' indicates the source of the routing information, not the subnet mask.

Bprefix

The 'prefix' combines the network address and its length (e.g., /24), implicitly defining the mask, but it is not the mask component itself.

Cmetric

The 'metric' is a value used by routing protocols to determine the best path to a destination network, not the subnet mask.

Dnetwork maskCorrect

The 'network mask' (or subnet mask) component in a routing table entry specifies which portion of an IP address corresponds to the network ID, determining the size of the network or subnet.
