Two small parallel plane square surfaces, each measuring $4 \mathrm{~mm} \times 4 \mathrm{~mm}$ are placed $0.5 \mathrm{~m}$ apart (centre to centre) with $30^{\circ}$ angle between the radial distance and both the surface normals. The view factor between the two surfaces is

(A) $1.53 \times 10^{-5}$

(B) $1.76 \times 10^{-5}$

(C) $3.82 \times 10^{-3}$

(D) $4.41 \times 10^{-3}$
