The Ethernet option is not showing up in networks. And I tried to add the interface from the dropdown (... dropdown), but no interface with USB 10/100/1000 LAN is available. I also tried re-imaging, but with no luck. I remember the ethernet option being available some time ago; I might have deleted it accidentally. How can I get this option back to connect to the internet using an Ethernet cable?

Have you connected an Ethernet source? When I open my computer's dialogue box as in your example, I get the same list as you with the addition of an Ethernet connection listed under its product name, i. e., "Broadcom NetXtreme Gigabit Ethernet Controller". I don't remember if it was an option in the Network Settings before, because I just plugged it in and it worked. Which I believe means you don't have to add it ahead of time, though you can delete it or make changes once it is in the list.
There need to be another interface in the list "Ethernet" or "USB 10/100/1000 LAN" to connect with ethernet cables.
Ethernet port interface with 10/100/1000 LAN is removed
