(A) m=-2, so image is magnified and inverted. Which is possible only for concave mirror. since image is i inverted so it will be real.
(B) M=−

, so image is inverted and diminished. since image is inverted, so it will be real, and the mirror will be concave.
(C) M =+2, image is magnified so the mirror will be concave. Image is erect so it will be virtual.
(D) m=+

, image is erect so image will be virtual. Image is virtual and diminished, so the mirror should be convex.
