on all data transmission
B
only on data transmission on remote networks
C

D
None of the above
Explanation: 

Detailed explanation-1: -If you want to access the management functions from a remote network, it needs a default gateway. If you don’t plan to use the management functions or only plan to use them on the directly attached network, a default gateway is not needed.

Detailed explanation-2: -When a host wants to reach a destination that is outside of its own network, it has to use a default gateway. We use a router or multilayer switch (that’s a switch that can do routing) as a default gateway. Above we have two hosts connected to a switch. We only have network 192.168.

Detailed explanation-3: -Windows computers can’t use multiple default gateways.-windows.microsoft.com/en-us/windows/… The logical explanation is that according to the original design principles of the Internet and TCP/IP, there is supposed to be only one global Internet and therefore it doesn’t matter which default gateway is chosen.

Detailed explanation-4: -A default gateway makes it possible for devices in one network to communicate with devices in another network. If a computer, for example, requests a web page, the request goes through the default gateway before exiting the local network (LAN) to reach the internet.
