The correct answer is: B. May include the image of the horizon.
High oblique photographs are taken with an angle of tilt between 30° and 90° from the vertical. The image of the horizon is not always included in high oblique photographs, as the camera can be tilted upwards or downwards to capture a different view.

C. May not include the image of the horizon is correct, as the camera can be tilted upwards or downwards to capture a different view.
