\\\\(\ extbf{Explanation}\\\\)\\\\(\\bullet\\\\)The spherical aberration for a plano-convex lens will be minimum when the curved surface faces the object and then the light from the object will fall on the curved surface. \\\\(\\bullet\\\\)This is because the total deviation of the ray is distributed between the two surfaces. Th total deviation is shared by both the surfaces.Hence, the spherical aberration is smaller if the curved surface of the lens faces the object.The correct answer is option (B).
