Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The tag v1.0-rc is removed, and the repository now contains only one tag (v1.0) and three branches.
The command deleted the tag refs/tags/v1.0-rc. After deletion, the tag is no longer available. The other refs (branches and tags) remain unchanged. The repository now has only one tag: v1.0. The branches main, develop, and feature/new-feature still exist.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The tag v1.0-rc is removed, but the commit it pointed to is also deleted from the repository.
Why it's wrong here
Deleting a tag does not delete the commit; the commit remains reachable via other refs if any.
✗
The tag v1.0-rc is removed, and the branch feature/new-feature is also deleted because it was the same object.
Why it's wrong here
The delete command only affects the specified ref; other refs are unaffected.
✓
The tag v1.0-rc is removed, and the repository now contains only one tag (v1.0) and three branches.
Why this is correct
The delete command removes the tag v1.0-rc. The other refs remain, so there is one tag and three branches.

Read the scenario before looking for a memorised answer.
✗
The command fails because the tag does not exist.
Why it's wrong here
The exhibit shows the tag existed before deletion; the command succeeded.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
