If the depth of neutral axis for a singly reinforced rectangular section is represented by kd in working stress design, then the value of k for balanced section_______________?
(A) depends on as, only
(B) depends on aCbC only
(C) depends on both crst and acbc
(D) is independant of both ast and acbc where d is the effective depth, ast is per-missible stress in steel in tension and ocbc is permissible stress in concrete in bend¬ing compression
