The human embryo is about one inch in length after

Options

A. 2 weeks
B. 4 weeks
C. 6 weeks
D. 8 weeks

Explanation

To determine the length of the human embryo at various stages, we can analyze the information provided in the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the length of the human embryo at different weeks of development: 2 weeks, 4 weeks, 6 weeks, and 8 weeks.

2. **Length After 2 Weeks**: At 2 weeks, the embryo is still in the early stages of development. Typically, at this stage, the embryo is not yet measurable in inches.

3. **Length After 4 Weeks**: By 4 weeks, the embryo has grown, but it is still relatively small. Generally, it is around 0.5 inches (approximately 1.27 cm) in length.

4. **Length After 6 Weeks**: At 6 weeks, the embryo continues to grow. It is usually about 1 inch (approximately 2.54 cm) in length.

5. **Length After 8 Weeks**: After 8 weeks, the embryo is more developed and measures about 1.5 inches (approximately 3.81 cm). At this stage, significant developments such as the formation of limbs, ears, and facial features occur.

6. **Conclusion**: The human embryo is about 1 inch in length after 6 weeks of development.

### Final Answer:
The human embryo is about 1 inch in length after 6 weeks.
