In a R.C section under flexure, the assumption that “a plane section before bending remains plane after bending” leads to
(a) Strain distribution being linear across the depth
(b) Stress distribution being linear across the depth
(c) Both stress and strain distribution being linear across the depth
(d) Shear stress distribution being uniform along the depth
