C Correct answer
Explanation

Segmentation, which breaks data into smaller manageable pieces, occurs at the Transport Layer (Layer 4) of the OSI model. TCP and UDP operate at this layer and handle segmentation of data streams. The Data Link Layer handles framing, and the Physical Layer deals with raw bit transmission. Option D has a typo ('Netwrok') but refers to Network Layer, which handles routing, not segmentation.
