When a frame arrives at a NIC $($Network Interface Card$),$ the NIC checks the frame's destination MAC $($Media Access Control$)$ address to see whether it matches its built$-$in MAC address. NIC only permits inbound communications to pass through the interface if the destination MAC address meets which of the following criteria? $($More than one criterion applies$).$

a$.$ The destination MAC $($Media Access Control$)$ matches the NICs built$-$in MAC address.

b$.$ The destination MAC $($Media Access Control$)$ is a broadcast address $($FF$-$FF$-$FF$-$FF$-$FF$-$FF$).$

c$.$ The NIC is in a special mode called promiscuous.
