To answer this question, you need to understand the OSI (Open Systems Interconnection) model. The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers.
The MAC (Media Access Control) sublayer is a part of the Data Link layer, which is the third layer of the OSI model. The Data Link layer is responsible for the reliable transfer of data over a physical link. It provides error detection and correction, as well as flow control between two directly connected nodes.
The Data Link layer is divided into two sublayers: the Logical Link Control (LLC) sublayer and the MAC sublayer. The LLC sublayer handles the flow control and error checking for the data link, while the MAC sublayer is responsible for controlling access to the physical medium.
Therefore, the correct answer is:
C. Data Link
