A convex lens and concave lens are kept in contact and the combination

1.	A convex lens and concave lens are kept in contact and the combination is used for the formation of image of a body by keeping it at different places on the principal axis. The image formed by this combination of lenses can be : (A) Magnified, inverted and real(B) Diminished, inverted and real(C) Diminished, erect and virtual(D) Magnified, erect and virtual
Answer» Correct option (A)(B)(C)(D) Explanation: Combination may behave converging In that case (a), (b) & (d) are possible . If combination behaves like diverging c will be correct. So all the options are correct.
