None of these
Correct Answer
A. ArrowExplanation
When a mouse on a surface is moved, the arrow on the screen also moves. The arrow is the graphical representation of the mouse cursor on the computer screen. As the physical mouse is moved, it sends signals to the computer, which in turn moves the arrow on the screen accordingly. This allows the user to navigate and interact with different elements and icons on the screen. The other options, such as "Icon" and "Mouse pad," do not accurately describe the direct relationship between the physical movement of the mouse and the movement of the arrow on the screen.Rate this question:
