Which statement regarding the uterus is true:

Correct Answer: A

Rationale: The correct answer is A: it is pear-shaped. The uterus is indeed pear-shaped in structure, with a wider upper part called the corpus and a narrower lower part called the cervix. The pear shape allows for the expansion required during pregnancy. The other choices are incorrect: B is inaccurate as the superior extremity is the fundus, not the corpus; C is incorrect as the vagina is connected to the cervix, not the inferior extremity; D is wrong as the uterus is located centrally in the pelvis.

Correct Answer: B

Rationale: The correct answer is B: uterus. Specialization of parts of the developing baby takes place in the uterus during pregnancy. The uterus is where the fertilized egg implants and the embryo develops into a specialized structure known as a fetus. The other choices (A: ovary, C: testis, D: pancreas) do not play a direct role in the development of the baby during pregnancy. The ovary is involved in producing eggs, the testis produces sperm, and the pancreas is responsible for producing digestive enzymes and hormones, but they are not directly involved in the specialization of parts of the developing baby.
