Answer:
Correct option is
C
Types of Image - real, Orientation of Image - inverted, Size of Image Compared to Object - smaller.
The image produced by a pinhole camera is usually smaller than the object and appears to be inverted on both the vertical and horizontal axis when compared to the actual object. The image itself can be called "real" because it is visible on the screen.
