Explanation

Option B is correct because the statement describes the mechanism of routing protocol priority but misstates its function. The actual function of routing protocol priority (known as Administrative Distance in Cisco terminology) is to select which single best route gets installed into the routing table when the same destination is learned from multiple protocols - not merely to assign priorities so that routes "can have a selected priority," which is a circular and incomplete description.

Option A is wrong because, while the statement sounds plausible on the surface, the stated purpose ("so that it can have a selected priority") confuses the means with the end. Priority assignment is the mechanism, not the goal; the goal is decisive route selection for the routing table.

Memory tip: Think of routing protocol priority as a tiebreaker judge, not just a name-tag printer. Its job isn't to label routes with numbers - it's to pick a winner and install exactly one route in the routing table. Any statement that stops at "assigning priority" without mentioning that the router then chooses the lowest-AD route for the table is incomplete and therefore false.
