A beam section is shown in the figure below. The beam is made with normal weight concrete $($NWC$)$ with $f^{\text{'}}c=5,000$ and $fy=75,000$ and reinforced with a layer of $3$ No$.11$ bars. Take $b=14-$in and $h=21-$in and $r=3-$in$.$

The minimum reinforcement ration $(r$ min$)$ in percent for this section is mostly near

$0\mathrm{.}28$

$0\mathrm{.}29$

$1\mathrm{.}86$
