Center of Projection in Parallel projection
 A is at finite distance B is at infinite distance C is at same distance of actual object D is near than the actual object
Explanation:

Detailed explanation-1: -It is an arbitrary point from where the lines are drawn on each point of an object. If the cop is located at infinity, all the lines are parallel and the result is a parallel projection.

Detailed explanation-2: -In Perspective Projection the center of projection is at finite distance from projection plane. This projection produces realistic views but does not preserve relative proportions of an object dimensions.

Detailed explanation-3: -If the distance between the Centre of Projection (COP) to the projection plane is finite, the projectors are not parallel to each other. This kind of projections is called perspective projection.

Detailed explanation-4: -Orthographic Projection: Observer at infinite distance from the object.

Detailed explanation-5: -In three-dimensional geometry, a parallel projection (or axonometric projection) is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other.
