Automatic repeat request error management mechanism is provided by ___

1.	Automatic repeat request error management mechanism is provided by ________(a) logical link control sublayer(b) media access control sublayer(c) network interface control sublayer(d) application access control sublayerI have been asked this question in a national level competition.I want to ask this question from Data Link Layer topic in division OSI Model of Computer Network
Answer» Correct option is (a) logical link control sublayer The explanation is: The logical link control is a sublayer of data link layer whose main function is to manage traffic, flow and error control. The automatic repeat request error management mechanism is provided by the LLC when an error is FOUND in the RECEIVED FRAME at the receiver’s end to inform the sender to re-send the frame.
