The _________ connects the placenta on the wall of the uterus to the navel of the baby and provides the growing baby with oxygen and nourishment from the mother.

Options

A. Umbilical cord
B. Foetus
C. Zygote
D. Embryo

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the structure that connects the placenta, which is attached to the wall of the uterus, to the navel of the baby. This structure is responsible for providing the baby with oxygen and nourishment from the mother.

2. **Identifying Key Terms**: The key terms in the question are "placenta," "navel of the baby," "oxygen," and "nourishment." The placenta is an organ that develops in the uterus during pregnancy and plays a critical role in fetal development.

3. **Analyzing the Options**: The options given are:
- A) Umbilical cord
- B) Fetus
- C) Zygote
- D) Embryo

4. **Evaluating Each Option**:
- **Fetus**: This is the developing baby itself, not a connecting structure.
- **Zygote**: This is the fertilized egg, which develops into an embryo, but it does not connect to the placenta.
- **Embryo**: This is the stage of development after the zygote, but again, it does not serve as a connection.
- **Umbilical cord**: This is the flexible tube that connects the placenta to the baby’s navel, allowing for the transfer of oxygen and nutrients.

5. **Conclusion**: Based on the analysis, the correct answer is **A) Umbilical cord**. This structure is essential for the baby's development as it facilitates the exchange of oxygen and nutrients from the mother.
