A Correct answer
Explanation

The data link layer (Layer 2) is responsible for packaging bits into frames, adding physical (MAC) addressing for node-to-node delivery within the same network segment. Frames are the protocol data units (PDUs) at this layer. The transport layer works with segments, and the physical layer handles raw bits.
