a.Left open with sharp ends
b.Cut off flush at the top step only
c.Returned to the wall or terminated in a newel/safety terminal so clothing cannot catch

Giải thích
Handrail ends must return to the wall or end in a newel post or safety terminal so that loose clothing, bags, or hands cannot catch on an open end. Leaving sharp open ends, cutting off only at the top, or removing the rail at the landing all create hazards and break continuity.
