B

The destination MAC address of a broadcast frame is ff:ff:ff:ff:ff:ff, which is a special address that represents a broadcast to all devices on the network.

When a device wants to send a broadcast frame, it sets the destination MAC address of the frame to ff:ff:ff:ff:ff:ff. This tells the network hardware to send the frame to all devices on the network, regardless of their MAC addresses.

In contrast, unicast frames are sent to a specific MAC address of a single device, and multicast frames are sent to a group of devices that share the same multicast MAC address.

The other MAC addresses listed in the answer choices are not used for broadcast frames. Some of them may be used for specific purposes, such as the Cisco proprietary MAC address 00:00:0c:07:ac:01, which is used for Virtual Local Area Network (VLAN) tagging, or the multicast MAC address 01:00:5e:00:00:01, which is used for the all-hosts multicast group. However, none of these addresses represent a broadcast to all devices on the network.
