A possible reason why Sam can only see some of the issues on the project’s Kanban board but sees all of them in the issue search is that the column mapping of the board does not include all the statuses of the different workflows used by the issue types. Column mapping determines which statuses are mapped to which columns on a board, and only issues with mapped statuses are displayed on the board. If an issue type has a workflow with a status that is not mapped to any column, then it will not appear on the board. Board permissions, issue-level security, and workflow conditions do not affect the visibility of issues on a board, as they apply to both the board and the issue search. Therefore, the correct answer is B. References: [Configuring columns], [Configuring workflows]
