In a reinforced concrete section, the stress at the extreme fibre in compression is $5.80 \mathrm{MPa}$. The depth of neutral axis in the section is $58 \mathrm{~mm}$ and the grade of concrete is $\mathrm{M} 25$. Assuming linear elastic behavior of the concrete, the effective curvature of the section (in per $\mathrm{mm}$ ) is
(A) $2.0 \times 10^{-6}$
(B) $3.0 \times 10^{-6}$
(C) $4.0 \times 10^{-6}$
(D) $5.0 \times 10^{-6}$
