Refer to the exhibit. The output of the diff -u README.md-repo README.md command is shown. The original file was 165 lines long. How many lines are in the edited copy of the file?

Explanation

In unified diff format (diff -u), lines prefixed with '-' indicate removals and lines prefixed with '+' indicate additions. The @@ hunk headers show the original and new line ranges. Starting from the original 165 lines, the exhibit's diff output shows a net addition of 7 lines (more '+' lines than '-' lines across all hunks). Therefore: 165 + 7 = 172 lines in the edited file. This matches option C (172). Options A (162) and D (173) reflect incorrect arithmetic, and B (165) would mean no net change.
