Pick up the correct statement from the following: A. Aerial photographs may be either vertical or oblique B. Vertical photographs are taken with the axis of camera pointing vertically downward C. Vertical photographs are used for most accurate maps D. All the above

The correct answer is D. All the above.

Aerial photographs

may be either vertical or oblique. Vertical photographs are taken with the axis of camera pointing vertically downward, while oblique photographs are taken with the axis of camera pointing at an angle to the vertical. Vertical photographs are used for most accurate maps because they provide a more accurate representation of the ground surface.

Here is a brief explanation of each option:

• Option A: Aerial photographs may be either vertical or oblique. This is true because aerial photographs can be taken with the camera pointing vertically downward (vertical photographs) or at an angle to the vertical (oblique photographs).
• Option B: Vertical photographs are taken with the axis of camera pointing vertically downward. This is also true because vertical photographs are taken with the camera pointing straight down from the aircraft.
• Option C: Vertical photographs are used for most accurate maps. This is true because vertical photographs provide a more accurate representation of the ground surface than oblique photographs.

I hope this helps!
