Solution

The correct option is D The image formed using a pinhole camera is always inverted.
The pinhole camera is the simplest kind of camera. It does not have a glass lens. It makes use of an extremely small opening (a pinhole-sized opening) which also serves as it's lens. The pinhole size should be very small to get sharper image. The image formed using a pinhole camera is always inverted due to the rectilinear propagation of light.
