Correct answer: B
On a broadcast network, IS-IS elects a Designated Intermediate System (DIS) to reduce the number of adjacencies and the amount of LSP flooding. The DIS's primary role is to create a 'pseudonode' LSP that represents the broadcast segment itself and lists all the routers attached to it. This simplifies the link-state database, as each router only needs to see the pseudonode instead of forming adjacencies with every other router on the segment.
