If the depth of actual neutral axis of a doubly reinforced beam

If the depth of actual neutral axis of a doubly reinforced beam

(A) Is greater than the depth of critical neutral axis, the concrete attains its maximum stress
earlier

(B) Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum
stress earlier

(C) Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum
stresses simultaneously

(D) All the above

The correct Answer Is
(D) All the above
