Answer options

• A. PDUs
• B. Bits
• C. Sequences
• D. Segments
• E. Packets
• F. Frames

Correct answer: B, D, F

Explanation

The correct terms for data at Layer 1, 2, and 4 are Bits, Segments, and Frames. Bits refer to Layer 1, Segments represent Layer 4, and Frames pertain to Layer 2. The other options, PDUs, Packets, and Sequences, do not accurately correspond to the specified layers of the OSI model.
