Perspective centre relates to A. Parallel projection B. Orthogonal projection C. Central projection D. None of these

The correct answer is C. Central projection.

Central projection is a type of projection in which all rays from an object to the projection plane pass through a single point, called the center of projection. This type of projection is used to create perspective drawings, which give the illusion of depth.

Parallel projection is a type of projection in which all rays from an object to the projection plane are parallel. This type of projection is used to create orthographic drawings, which are two-dimensional representations of three-dimensional objects.

Orthogonal projection is a type of parallel projection in which the projection plane is perpendicular to the object. This type of projection is often used in engineering and architecture.

None of these is not a correct answer.
