2. What modulus of elasticity is predicted by ACI 318 for normal weight concrete with a compressive strength of \( 3000 \mathrm{lbf} / \mathrm{in}^{2} ? \) (A) \( 0.26 \times 10^{6} \mathrm{psi} \) (B) \( 1.9 \times 10^{6} \mathrm{psi} \) (C) \( 2.8 \times 10^{6} \mathrm{psi} \) (D) \( 3.2 \times 10^{6} \mathrm{psi} \)
