In the modified Cleaves method, the left ASIS is placed closer to the imaging table than the right ASIS, resulting in the left hip demonstrating a narrowed obturator foramen. Option 1 is correct. The iliac wing will not be widened because it is not affected by the positioning. Option 2 is incorrect. The iliac spine without pelvic brim superimposition will not be seen on this projection.

Option 4 is incorrect.
