A$)22$

B$)34$

C$)40$

As per ACI Code, the reinforcement in a column should not be less than

$($A$)0\mathrm{.}7\%$ of cross$-$sec$-$tional area

B$)0\mathrm{.}6\%$ of cross$-$see$-$tional area

C$)0\mathrm{.}5\%$ of cross$-$sec$-$tional area

D$)1\%$ of cross$-$scotional area

Load$-$moment curves are plotted in Fig. for columns of three different lengths, all loaded with the same end eccentricity, c$.$ The load$-$moment curve $O-$ A represents

Ar a moderate length colum

C$)$ a long length column

D$)$ none of the above
