B is correct.
Proirity and IP both influence who will become the DR.
Take this scenario.
If you have 10 routers on a LAN with their defaults (meaning they all have a
priority of 1 for DR election)
how will the DR be chosen purely on Priority ? How will they know the
priority of the other router interfaces on that network ?
During DR elecetion priority is first looked at.
If there ia a tie on priority then the Router ID, which is usally the high
interface ip or loopback IP (depending whether loopback are configured -
highly recommended)
Each router is able to see each others priority value via hello packet
exchanges which where the election takes place.
hope that helps.
