A Correct answer
Explanation

ls -lR recursively lists all files with ownership details, grep filters for lines containing your username, and wc -l counts the matching lines. This correctly counts files you own across all directories. Option B uses non-standard 'cnt' command, Option C shows numeric IDs without counting, and Option D is just a sorted listing.
