Answer 1

The correct option is D A-3, B-1, C-2

Pinhole camera has no lens; it has just a whole which allows the light to come in and make an image on the screen.

A magnifying lens uses a convex lens. It forms a virtual and enlarged image for an object placed close to it.

A peephole uses a concave lens, which helps to see a wide angle view of the outside.
