Which statement about adding a serial node in the Node Window is correct?

• A. Alt/Option+N loads a version of your grade.
• B. Right-clicking in the node window opens Add Serial Node.
• C. There is a menu option to add a serial node from the top bar only.
• D. Alt/Option+N loads a version of your grade and right-clicking does not provide the option to add a serial node.

Answer: (D)

In the Node Window, mixing version control with node insertion can be confusing, but they are separate actions. Alt/Option+N is a shortcut tied to the grading versioning system, so pressing it loads a different saved version of your grade rather than adding or modifying nodes. To add a serial node, you don’t rely on right-clicking here—that option isn’t provided in this context. You’d use the appropriate top-bar menu item or a different shortcut to insert a serial node. So this statement captures the correct behavior: the shortcut loads a grade version, and right-clicking does not present an option to add a serial node.
