As the degree of femoral abduction increases, the femoral neck appears shorter due to foreshortening, and the greater trochanter moves closer to the femoral head. However, the lesser trochanter remains in profile, and there is no change in the appearance of the obturator foramen. Therefore, choices 2 and 3 are correct, making option B the best choice. Choice 1 is true but not the only correct option, and choice 4 is incorrect.
