A uniformly charged and infinitely long line having a liner charge density \( \lambda \) is placed at a normal distance \( y \) from a point \( O \). Consider a sphere of radius \( R \) with \( O \) as centre and \( Ry \). Eleetric flux through the surface of the sphere is
(A) zero
(B) \( \frac{2 \lambda R}{\varepsilon_{0}} \)
(C) \( \frac{2 \lambda \sqrt{R^{2}-y^{2}}}{\varepsilon_{u}} \)
(D) \( \frac{\lambda \sqrt{R^{2}+y^{2}}}{E_{0}} \)
