Why each option

In the Junos OS command-line interface, the Ctrl + u keyboard shortcut allows users to erase the entire current command from the cursor position to the beginning of the line.

ACtrl + a

Ctrl + a moves the cursor to the beginning of the line, it does not erase the command.

BCtrl + e

Ctrl + e moves the cursor to the end of the line, it does not erase the command.

CCtrl + uCorrect

Ctrl + u is a standard command-line shortcut used in many Unix-like environments, including Junos OS, to delete all characters from the cursor's current position to the beginning of the line.

DCtrl + w

Ctrl + w deletes the word to the left of the cursor, not the entire current command.
