Understanding the Question

Fetal development is the stage of development that follows the embryonic stage after fertilization. This question seeks to identify the correct time frame during which this significant stage of development occurs.

Breakdown of the Choices

1. 0-3 weeks: This period refers to the pre-embryonic phase. The fertilized egg implants, and basic body structures start to form but it is not fully fetal development yet.
2. 4-8 weeks: During this time, significant embryonic development occurs, laying the groundwork for the fetal stage, but it is still considered the embryonic period.
3. 0-3 months: This encompasses both embryonic and early fetal development; however, not all of this time qualifies as fetal development.
4. 3-9 months: This is the correct duration in which fetal development occurs, as the fetus develops major organs and systems during this period.

Conclusion

Fetal development primarily occurs during the 3-9 months time frame after fertilization. Hence, the answer is:

Final Answer: 3-9 months
