A square surface of side \( L \) meter in the plane of the paper is placed in a uniform electric field \( E(\mathrm{volt} / \mathrm{m}) \) acting along the same plane at an angle \( \theta \) with the horizontal side of the square as shown in figure. The electric flux linked to the surface, in units of volt \( \mathrm{m} \) is
(a) \( E L^{2} \)
(b) \( E L^{2} \cos \theta \)
(c) \( E L^{2} \sin \theta \)
(d) zero
