The concept here is runway surface condition and how moisture or ice affects friction and braking performance. A dry runway means there’s no moisture or other contaminants on the surface, so friction is at its highest and braking action is at its best. That’s why the level that represents no moisture is the correct choice for a dry surface. The other possibilities describe wetter or icy conditions, which would not be dry and would reduce braking effectiveness.
