Answer:
Explanation: The transport layer assembles the packets into data, and prepares the data for the session layer
above. The Network layer determines the route of moving data. Remember the Network layer is layer 3, and
routers work on layer 3. The network layer includes routing functions, and keep this in mind when the question
says determines the best way to move data. On the datalink layer, the actual transmission occurs.
The physical layer does not modify the data and package it, not is involved with addressing and routing, so it
does not apply. The session layer also does not modify data or determine routes or transmit data, so it would not
apply to any of the above.
