With reference to a computer mouse, the left button helps to _____ the item, while the right button helps to ______ the menu.

Correct option is A

In a computer mouse, the left button is primarily used to select items such as files, folders, text, or icons. The right button is used to display a context menu that offers additional options relevant to the selected item.

Important Key Points:

1. Left-click is used for selecting, dragging, and double-clicking to open items.
2. Right-click opens shortcut or context menus, which vary based on where you click.
3. These functions are standard in all graphical user interfaces (GUI) like Windows, macOS, and Linux.

Knowledge Booster:

• The left button does not "display" menus—it selects or opens items.
• The right button is not for selection—it displays a menu.
• Read and write terms apply more to data operations in memory or storage, not to mouse functions.
