As illustrated below, the Source Address field of an Ethernet frame is six bytes in length. This is because A) this field identifies the MAC address of the sending device in the local network and the address includes six hexadecimal codes and each code converts to 8 bit binary values. A) this field identifies the MAC address of the sending device in the local network and the address includes six hexadecimal codes and each code converts to 8 bit binary values. B) this field must be able to accommodate either IPv4 and IPv6 addresses depending on which is used at the Network layer C) error checking schemes used in Ethernet and Wi-Fi LANs use this field to to detect data transmission errors D) the media access control mechanism used in Ethernet LANs uses this field to identify the type of data included in the frame's data field
