Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
git blame <filename> or git log -p <filename>
Why this is correct
Correct. 'git blame' shows line authorship, and 'git log -p' shows patch/diff history per file.
- ✗
git history --routing-policy
Why it's wrong here
No such Git command exists.
- ✗
git diff --author
Why it's wrong here
git diff compares trees or commits, not file-level line history by author.
- ✗
git status --verbose
Why it's wrong here
git status shows the working tree status, not historical line changes.
