Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
git reset HEAD~1 (or git reset --mixed HEAD~1)
'git reset --soft HEAD~1' or 'git reset HEAD~1' resets the commit while keeping working tree files modified/staged depending on flags. 'git reset HEAD~1' defaults to mixed (keeps changes unstaged).
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 reset --hard HEAD~1
Why it's wrong here
--hard destroys all working directory changes.

Why it's wrong here
This discards local work and switches to master.
