Answer 1

The correct option is B (ii) and (iv) only

A pinhole camera is a simple camera without a lens but with a tiny aperture. A pinhole is effectively a light proof box with a small hole in one side. Light from a scene passes through the aperture and projects an invested image on the opposite side of the box.
The image of a pinhole camera may be projected onto a translucent screen for real time viewing.
