Network interface cards are built into new computers and are integrated into the motherboard during manufacture.
Step-by-step explanation:
LAN: The option 1 is not valid because, it is connecting computers locally and it can be done only after designing the entire system and placed in a position where it needs to be connected.
Peripherals: These are all external device which is used for input and output. So it is not integrated during manufacture.
NIC: Network interface cards are the right answer since it is built during the manufacture itself. It is a card which allows the computer to get connected with the network.
Addresses: This option is generic ie. there is no clarity whether it belongs to physical or logical address.
