The correct answer is beyond C.Concept:Spherical mirror:A spherical mirror is a mirror that has the shape of a piece cut out of a spherical surface.There are two types of spherical mirrors: concave, and convex. Explanation:Concave mirror:It is part of a whole spherical mirror that reflects light from the hollow part.It is a converging mirror because it converges the incident rays at a point.When the object is between C (Centre of curvature) and F (focus):Characteristics of Image Formed:Position: Beyond CSize: Magnified/ enlarged Nature: Real and invertedAdditional Information All six cases of image formation by the concave mirror:Object positionImage positionNature of imageSize of imageAt infinityAt FReal and inverted Point sized Beyond CBetween C and FReal and invertedDiminishedAt CAt CReal and inverted Same size Between C and FBeyond CReal and inverted Magnified At FAt infinity Real and invertedHighly magnified Between F and POn the backside of the mirrorVirtual and erect Magnified Convex mirror: It is part of a whole spherical mirror that reflects light from the bulged-out part.It diverges the incident rays.
