An extended object of size 2 cm is placed at a distance of d (cm) in medium (refractive index n = 3) from pole, on the principal axis of a spherical curved surface.The medium on the other side of refracting surface is air (refractive index n = 1).
For d = 20 cm, The size of image is
(A) 1 / 6 cm
(B) 2 / 15 cm
(C) 6 / 5 cm
(D) 3 / 2 cm
