Pick up the correct statement from the following :

• The principal point coincides with plumb point on a true vertical photograph
• The top of a hill appears on a truly vertical photograph at greater distance than its bottom from the principal point
• The top of a hill is represented on a vertical photograph at larger scale than the area of a nearby valley
• The planimetric displacement of the point due to relief on a truly vertical photograph is directly proportional to its distance from the principal point and also its elevation
• All the above.
