Answer: (C)

Verified step by step guidance

1. Understand the concept of homologous structures: Homologous structures are anatomical features in different sexes that share a common embryonic origin but may have different functions in adults.
2. Review the embryonic development of male and female reproductive systems: Both systems develop from the same structures during early embryogenesis, influenced by the presence or absence of certain hormones like testosterone.
3. Identify the male scrotum's embryonic origin: The scrotum develops from the labioscrotal swellings in males under the influence of testosterone.
4. Compare the female structures to the male scrotum: In females, the labioscrotal swellings develop into the labia majora, making them homologous to the male scrotum.
5. Conclude that the labia majora is the correct answer: The labia majora and the scrotum share a common embryonic origin, making them homologous structures.
