You want to copy a file named report.txt to a directory /backup and preserve the file's timestamp. Which command is correct?

Acp report.txt /backup -p

Bcp -p report.txt /backup

Ccp /backup report.txt -p

Dcp report.txt -p /backup

Step-by-Step Solution

Solution:

Step 1: Recall cp command structure
The command is 'cp', options come next, then source file, then destination directory.
Step 2: Identify correct option placement
'-p' preserves timestamps and must come immediately after the command, before arguments.
Step 3: Validate each option
cp report.txt /backup -p places '-p' after destination, which is incorrect. cp /backup report.txt -p reverses source and destination. cp report.txt -p /backup places '-p' between arguments, which is invalid.
Final Answer:
cp -p report.txt /backup -> Option B
Quick Check:
Command + options + source + destination [OK]

Quick Trick: Options always come right after the command [OK]
