The critical bending compressive stress in the extreme fibre of a structural steel section is $1000 \mathrm{MPa}$. It is given that the yield strength of the steel is $250 \mathrm{MPa}$, width of flange is $250 \mathrm{~mm}$ and thickness of flange is $15 \mathrm{~mm}$. As per the provisions of IS:800-2007, the non-dimensional slenderness ratio of the steel cross-section is

(A) 0.25

(B) 0.50

(C) 0.75

(D) 2.00
