4. Quick Check:

   git branch -d safely deletes merged branches [OK]

Hint: Use -d to delete merged branches safely [OK]

Common Mistakes:

• Confusing -d with -D which force deletes
• Thinking it deletes remote branches
• Assuming it deletes unmerged branches

2. Which command correctly force deletes a local branch named bugfix?
