The correct answer to this question is A. NIC (Network Interface Card).
A Network Interface Card (NIC) is a hardware component that connects a computer to a network. It is installed in a computer's motherboard and provides a physical connection between the computer and the network.
A default gateway is the IP address of the device on a network that provides access to other networks. This device is usually a router that connects the local network to the internet or another network.
When a computer wants to communicate with a device on another network, it sends the data to its default gateway. The default gateway then forwards the data to the appropriate device on the other network.
In order for a computer to connect to its default gateway, it must have a NIC installed and configured with the appropriate network settings, including an IP address, subnet mask, and default gateway address. Once these settings are configured, the computer can communicate with other devices on the same network and access the internet or other networks through its default gateway.
Switches and routers are also important networking devices, but they do not directly connect a computer to its default gateway. A switch is used to connect multiple devices on the same network, while a router is used to connect different networks together. A cable modem is used to connect a network to the internet through a cable provider's infrastructure.
