Why each option

The question asks which route type is given highest priority when a router builds its routing table for a particular destination subnet.

AStaticCorrect

Static routes typically have the lowest administrative distance (e.g., 1 on Cisco routers) compared to dynamic routing protocols like OSPF (110) or BGP (20-200), making them preferred when multiple routes to the same destination exist. Furthermore, a route with a more specific prefix length will always be preferred over a less specific one, regardless of administrative distance, but among routes of equal specificity, administrative distance dictates precedence.

BBGP

BGP routes have a higher administrative distance than static routes, meaning they are typically less preferred.

COSPF

OSPF routes have a higher administrative distance than static routes, meaning they are typically less preferred.

DDefault

A default route (0.0.0.0/0) is the least specific route and is only used as a last resort when no other more specific route (including static, OSPF, or BGP routes) matches the destination IP address.
