Step 1: Understanding clipboard operations
The clipboard is a temporary storage area used to transfer text or data between locations in a document or between applications.
Step 2: Distinguishing between copy-paste and cut-paste
Copy & Paste: Duplicates the data; original remains unchanged.
Cut & Paste: Removes the original data and places it in a new location — used when moving data.
Step 3: Elimination of incorrect options
Bold: A formatting option, not related to moving text.
Justify: A paragraph alignment option.
Step 4: Conclusion
Since moving data requires removing it from its original location, the correct answer is (3) Cut & paste.
