Complete answer:
To solve the given question, we must be well aware of the obturator foramen.
The lower girdle which forms the hip is known as the pelvic girdle. It is the site at which the leg muscles get attached to the hip. It is also the site where the hindlimb is attached. The pelvic girdle is made up of the ilium, ischium and pubis. These 3 bones fuse together to form the hip girdle.
The pelvic girdle is a trough shaped group of bones. These bones create an opening in each leg which serves as passage for nerves and blood vessels.

Since now, we are well aware of the Obturator foramen, therefore, the correct answer to the question is Obturator foramen occurs in Pelvic Girdle.

Note: Here it must be noted that there is a slight difference in the shape of this Obturator foramen in the body of men and women. The obturator foramen is oval in shape in males whereas it is wider and more triangular in females. The shape is so to accommodate the fetus during pregnancy.
