Options

A. First month
B. First trimester
C. Fifth month
D. End of nine months

Answer

**Step-by-Step Solution:**

1. **Understanding Human Pregnancy Duration**: Human pregnancy typically lasts about nine months, which is divided into three trimesters.

2. **Development Timeline**:
- **First Month**: During the first month, the embryo's heart begins to form, but no movements are felt yet.
- **Second Month**: By the end of the second month, the fetus develops limbs, but movements are still not perceptible.
- **First Trimester (up to 12 weeks)**: Major organ systems are formed, but the first noticeable movements are not observed until later.

3. **Fifth Month**: It is generally around the fifth month (approximately 20 weeks into the pregnancy) that the first movements of the fetus, often referred to as "quickening," are felt by the mother. This is when the fetus has developed enough to exhibit noticeable movements.

4. **Conclusion**: Based on the developmental milestones, the first movements of the fetus are observed during the fifth month of pregnancy.

**Final Answer**: The first movements of the fetus are observed during the **fifth month**.
