A reinforced concrete tied column is subjected to a design axial compression force of 875 kips and a design bending moment about its strong axis of \( 740 \mathrm{ft}-\mathrm{kips} \). The column's cross section measures 30 in \( \times 18 \) in, and the distance from edge of column to center of steel in each face is \( 3 \mathrm{in} \). The concrete's specified compressive strength is \( 4000 \mathrm{psi} \), and the reinforcing steel is grade 60 . The required area of longitudinal steel is most nearly (A) \( 4.0 \) in \( ^{2} \) (B) \( 8.0 \mathrm{in}^{2} \) (C) 12 in \( ^{2} \) (D) 14 in \( ^{2} \)
