Match List I with List II. List I: (A) Physical layer, (B) Data link layer, (C) Network layer, (D) Presentation layer. List II: (I) Routing of signals, dividing outgoing messages into packets, acting as network controller, (II) Making and breaking connections, defining voltages and data rates, converting bits into electrical signals, (III) Synchronization, error detection and correction, assembling outgoing messages into frames, (IV) Works as a translating layer.

1. A(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
2. B(A)-(II), (B)-(III), (C)-(IV), (D)-(I)
3. C(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
4. D(A)-(II), (B)-(III), (C)-(I), (D)-(IV)
