The correct answer to the question is option 3, "Both 1 and 2". Let`s dissect each option to understand why.
Option 1 states that amnion contains fluid, which is correct. The amnion is a membrane that surrounds and protects the developing embryo, and it is filled with amniotic fluid. This fluid serves several purposes, including cushioning and protecting the embryo, maintaining a stable temperature, and allowing for movement.
Option 2 states that ultrasound scan can detect the sex of an embryo, which is also correct. During an ultrasound scan, the healthcare professional can typically determine the gender of the embryo based on the development of the reproductive organs. This can be helpful for parents who want to know the gender of their baby before birth.
Therefore, both statements in options 1 and 2 are correct, making option 3, "Both 1 and 2" the correct answer.
Alert - correct answer should be option 3.
