In theory of simple bending an assumption is made that plane sections before bending remain plane even after bending. This assumption implies that
A. Strain is uniform across the section
B. Stress is uniform across the section
C. Stress in any layer is proportional to its distance from the neutral axis
D. Strain in any layer is directly proportional to its distance from the neutral axis
