The data link layer is primarily responsible for transmitting messages between two nodes without any errors. It also performs error detection and correction to ensure the integrity of the data transmitted.

Other choices are incorrect. 
A is incorrect because the application layer provides streams of data to the data link layer. 
C is incorrect because error detection is a critical function of the data link layer. 
D is incorrect because the data link layer does not perform routing functions; this is the responsibility of the network layer. 
E is incorrect because the data link layer does not organize data into coherent messages for the application layer.
