In a basic Ethernet frame, there are several fields used to identify the source and destination of the data being transmitted. These fields include the Start of Frame (SOF), Frame Check Sequence (FCS), Destination Address (DA), and Source Address (SA).

The Destination Address (DA) and Source Address (SA) fields are both six-byte fields used to identify the MAC addresses of the devices communicating over the Ethernet network.

The Destination Address (DA) field identifies the MAC address of the device that should receive the data being transmitted, while the Source Address (SA) field identifies the MAC address of the device that is transmitting the data.

In Ethernet networking, each device on the network is assigned a unique MAC address, which is a six-byte address that is used to identify the device on the network. This MAC address is also known as a hardware address or physical address.

The DA field must be set to the MAC address of the device that should receive the data being transmitted, and the SA field must be set to the MAC address of the device that is transmitting the data. Both of these fields must be set to individual MAC addresses, meaning that they cannot be set to a multicast or broadcast address.

Therefore, the correct answer to the question is C. DA and D. SA.
