- A. intestines need this time to grow until week
- B. nutrient content of the blood is higher in this location.
- C. abdomen is too small to contain all the organs while they are developing.
- D. umbilical cord is much larger at this time than it will be at the end of pregnancy.
Correct Answer: C
Rationale: During early development of the fetus, the umbilical cord is relatively larger compared to later stages of pregnancy. This is because the umbilical cord plays a crucial role in providing necessary nutrients, oxygen, and removing waste products from the developing baby. As the pregnancy progresses, the blood vessels in the umbilical cord mature and shrink in diameter, leading to a decrease in its overall size compared to the early stages. The larger size of the umbilical cord in early pregnancy facilitates efficient nutrient exchange between the mother and the developing fetus, supporting the baby's growth and development.
