The sun represent the vanishing point in this one-point perspective photograph.
This refers to the point on the image plane drawing where the two-dimensional perspective projections of mutually parallel lines in three-dimensional space appear to converge.
In other word, from the linear perspective scheme, the vanishing point in paintings forms part of the point in fictive space which is supposed to appear the furthest from the viewer and the position at which all receding parallel lines meet.
Hence, in the photograph of sun setting at the end of a road, the sun represent the vanishing point in this one-point perspective photograph.
Therefore, the Option D is correct.
