The correct answer is so that the team owns the issue together, and participates in the solution together. The reason roadblocks are discussed in the daily standup meetings is so the team can deal with the issue together outside of the
meeting. The other responses are incorrect because none of them are reasons a roadblock would be discussed in standups. Roadblocks are not resolved in standups, nor is there a document requirement. The team should be solving roadblocks
and issues, not the ScrumMaster.
