A singly reinforced beam has breadth b, effective depth d, depth of neutral axis n and critical
neutral axis n1. If fc
and ft
are permissible compressive and tensile stresses, the moment to
resistance of the beam, is
(A) bn (fc
/2) (d - n/3)
(B) Atft
(d - n/3)
(C) ½ n1 (1 - n1/3) cbd²
(D) All the above
