<reasoning>

Identify the developmental timeline

During Human Prenatal Development, different organ systems form at specific times.

Locate reproductive organ formation

The reproductive organs begin differentiating and developing during the early fetal stage, specifically between weeks 8 and 15.

Evaluate the given options

• Weeks 3 to 7: Early embryonic stage focusing on gastrulation and basic neural tube formation.
• Weeks 8 to 15: The period when external genitalia and reproductive structures differentiate.
• Weeks 16 to 26 and 27 to 38: Later stages focused on growth, maturation, and preparation for birth.
