Explanation
Answer - D - The network layer has a header that contains the address of a destination host that is on another network.

Key Takeaway: The OSI layer is made of seven distinct layers. The network layer, also known as layer 3, has a header that has a network address, or the address of the destination. The packets are delivered using a combination of network address and datalink address. The layer 2 address represents the address of the next hop device on the way to the sender. This address is changed on each hop.
