Which of the following is not one of the three basic parts common to all frame types used by the data link layer?

Explanation:
Frame structure at the data link layer is built from three parts that repeat across technologies: a header, the data payload, and a trailer. The header carries addressing and control information, the data field carries the network-layer packet, and the trailer holds error-detection information such as a Frame Check Sequence. MTU size, on the other hand, is not a distinct part of the frame. It’s a limit that defines how large the data portion (and thus the entire frame) can be on a given link. Different technologies set different MTU values, but the frame’s fundamental components remain header, data, and trailer. So MTU size is not one of the frame’s basic parts.
