The region of the cross-section of a column in which compressive load may be applied without
producing any tensile stress, is known as the core of the cross-section. In circular columns the radius of the core, is
(a) One-half of the radius
(b) One-third of the radius
(c) One-quarter of the radius
(d) One-fifth of the radius
