The correct answer is D. Ctrl + Tab.
Ctrl + Tab is a keyboard shortcut that is used to move through each of the open tabs going to the right in Chrome browser. It is a very useful shortcut, as it allows you to quickly switch between tabs without having to use your mouse.
The other options are not correct. Ctrl + N is used to open a new tab, Alt + N is used to open a new window, and Alt + Tab is used to switch between open windows.
I hope this helps!
