The correct choice indicates a viewpoint that highlights the lack of value in asking Bryan to join. This suggests that the potential benefits or contributions Bryan could bring to the situation are perceived to be minimal or nonexistent. Choosing this answer conveys a clear stance that engaging Bryan would not be a productive endeavor, implying that such an invitation would not yield significant advantages for the group or situation at hand.

Understanding this option reflects an evaluative judgment about Bryan's potential contributions based on prior experiences, perceptions of his abilities, or the context of the request.
