A. Payload
The payload of an Ethernet frame contains the data from higher layers, such as the Internet Protocol (IP) and the Transport and Application Layers. The payload is located after the Ethernet header, which contains information such as the source and destination MAC addresses. The preamble and frame check sequence (FCS) are also part of the Ethernet frame, but they do not contain data from the higher layers. The preamble is used to synchronize the receiving device's clock with the sender's clock, while the FCS is used to verify the integrity of the data in the frame.
