Linux CLI - File and Directory Operations

AUse <code>ln</code> to create hard links because they share the same inode and save space.

BUse <code>ln -s</code> to create symbolic links because they are easier to manage.

CCopy the file multiple times to ensure backups are independent.

DUse <code>ln -s</code> with absolute paths to avoid broken links.

Step-by-Step Solution

Solution:

Step 1: Identify storage-saving method
Hard links share the same inode and file data, so multiple filenames point to the same data without duplicating storage.
Step 2: Compare with symbolic links and copies
Symbolic links only point to filenames and do not save storage if the original is deleted. Copying duplicates data, using more space.
Final Answer:
Use ln to create hard links because they share the same inode and save space. -> Option A
Quick Check:
Hard links save space by sharing inode [OK]

Quick Trick: Hard links share data, saving space for backups [OK]
