Which joint type is most likely to leak?Group of answer choicesconcaveflushV-jointweathered

The joint type that is most likely to leak is the flush joint. This is because flush joints are flat and do not have any overlapping parts, which makes it easier for water or other substances to seep through. The other joint types - concave, V-joint, and weathered - have shapes that are designed to help prevent leaks. For example, concave and V-joints have an inward curve that can help to trap any water that tries to get through, while weathered joints have a sloped shape that can help to direct water away from the joint. Therefore, out of these options, the flush joint is the most likely to leak.
