Answer options

• A. :s//dev/sdc//dev/sdd
• B. :s/\/dev\/sdc/\/dev\/sdd/g
• C. :s/\/dev\/sdc/\/dev\/sdd
• D. :%s/\/dev\/sdc/\/dev\/sdd

Correct answer: A

Explanation

Option A is the correct command for substituting all instances of /dev/sdc with /dev/sdd in vi. The other options either lack the global flag 'g' or are incorrectly formatted, making them ineffective for replacing all occurrences.
