Phrase: Physical Layer (PHY) | Statement: [200GBASE-KR2, subLayer, Physical Layer (PHY)]

Target entity: Physical Layer (PHY)
Context triple: [200GBASE-KR2, subLayer, Physical Layer (PHY)]

• A. OSI physical layer chosen
  The OSI physical layer is the lowest layer of the OSI model, responsible for transmitting raw bits over a physical medium through electrical, optical, or radio signals and defining the hardware specifications for network connections.
• B. Data Link Layer
  The Data Link Layer is the second layer of the OSI model responsible for reliable node-to-node data transfer, framing, and physical addressing (MAC) over a physical network medium.
• C. LTE MAC
  LTE MAC is the Medium Access Control layer in LTE networks responsible for scheduling, multiplexing, and managing radio resources between the physical layer and higher-layer protocols.
• D. Physical Coding Sublayer
  The Physical Coding Sublayer (PCS) is a sublayer of the physical layer in high-speed networks that encodes, decodes, and aligns data streams for reliable transmission over the physical medium.
• E. Ethernet PHY
  An Ethernet PHY is the physical layer transceiver chip or module that converts digital data from a MAC interface into electrical or optical signals for transmission over Ethernet cabling and vice versa.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
