Explanation

A unified diff chunk header (hunk header) follows the strict format: @@ -<start>,<count> +<start>,<count> @@. The minus side (-) represents the original file and the plus side (+) represents the new file, both using line numbers and line counts. Option D (@@ -88,10 +88,6 @@) correctly matches this format - it means starting at line 88, 10 lines were in the original, and 6 lines appear in the new version. Options A, B, and C are invalid because they use timestamp-style values instead of the required line-number,count integers.
