The ________ moves from the fallopian tube into the uterus and gets implanted and attaches itself to the wall of the uterus.

Options

A. Embryo
B. Oviduct
C. Zygote
D. Sperms

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about what moves from the fallopian tube into the uterus and gets implanted into the wall of the uterus.

2. **Identifying Key Terms**: The key terms in the question are "fallopian tube," "uterus," "implanted," and "attached."

3. **Understanding the Process**: In human reproduction, after fertilization occurs in the fallopian tube (where the sperm meets the ovum), a zygote is formed. This zygote undergoes several divisions and develops into an embryo.

4. **Embryo Development**: The zygote continues to divide and differentiate into an embryo. The embryo is the stage of development that occurs after the zygote and before it becomes a fetus.

5. **Implantation**: The embryo then moves from the fallopian tube into the uterus, where it implants itself into the uterine wall. This implantation is crucial for the development of the embryo.

6. **Conclusion**: Therefore, the correct answer to the question is "Embryo," as it is the structure that moves from the fallopian tube into the uterus and gets implanted into the wall of the uterus.

**Final Answer**: The **embryo** moves from the fallopian tube into the uterus and gets implanted and attaches itself to the wall of the uterus.
