The correct option is Polls because it is the native way in GitHub Discussions for participants to cast votes on proposals and view results that help prioritize a roadmap.

This feature lets maintainers add choices inside a discussion and allows contributors to vote directly in the thread. Results are tallied automatically which makes it easy to measure interest at a glance and to base planning decisions on clear counts rather than manual tallies.

Categories organize discussions into topical buckets and can control the format of posts in each bucket, yet they do not provide a voting mechanism.

Reactions allow emoji responses on posts and comments and they can signal sentiment, but they are not a structured voting tool and they do not offer multiple explicit options or aggregated tallies.

Labels are used to classify and filter items for triage and reporting, and they are not designed for voting in discussions.
