7. Note: Perspective projective mapping is imaging the 3D world coordinates to an image plane using a projective camera where all the rays pass through a camera center. Consider the camera center is at (0, 0, 0) and the image plane is parallel to XY plane and at a distance of f from it.

The Perspective projective mapping from world coordinates (1, 4, 5) to image coordinates, using a camera with focal length f = 0.25, is

a) (1/6, 1/3)
b) (1/20, 1/5)
c) (1/3, 1/6)
d) (1/6, 1/2)
