Correct Answer:
B. Ctrl + V
The 'paste' operation is fundamental in computing, allowing users to insert content that was previously 'copied' or 'cut' into a new location. This content is temporarily stored in a special memory area known as the clipboard. Once content is on the clipboard, it can be pasted multiple times. The standard keyboard shortcut for performing the paste action in most applications, including word processors and web browsers, is Ctrl + V.
- Ctrl + V is the correct shortcut for pasting content from the clipboard. The 'V' key is often chosen due to its proximity to 'C' and 'X' on the keyboard, facilitating quick copy-cut-paste operations.
- Ctrl + X is incorrect; this shortcut is used for 'Cut', which removes content.
- Ctrl + C is incorrect; this shortcut is for 'Copy', which duplicates content.
- Ctrl + Z is incorrect; this shortcut is used for 'Undo', which reverses the last action.
