B) 2 and 3 only
C) 2, 3, and 4 only
D) 1, 2, 3, and 4

1) The lesser tubercle should be in profile medially, not laterally.
2) The scapular body may be foreshortened due to patient positioning or projection angle, but this is not specific to an anterior tilt of the midcoronal plane.
3) The superior scapular angle should be inferior to the clavicle, so an anterior tilt of the midcoronal plane would result in the angle being lower.
4) Increased thoracic cavity superimposition may occur due to patient positioning or projection angle, but again, this is not specific to an anterior tilt of the midcoronal plane.

Therefore, the only two options that could be related to an anterior tilt of the midcoronal plane are 2) scapular body longitudinally foreshortened and 3) superior scapular angle superior to the clavicle.
