Which of the following statements is/are correct? 1. Amnion contains fluid. 2. Ultrasound scan can detect the sex of an embryo. Select the correct answer using the code given below.

Statement 1 is correct as the amnion is a membrane that forms the amniotic sac, which contains amniotic fluid [4]. This fluid surrounds the developing fetus, providing protection and nourishment while containing fetal cells used for genetic testing. Statement 2 is also correct. While human sex is genetically determined at fertilization, physical development of genital organs allows for detection via ultrasound [2]. Ultrasound scans can identify the sex of a fetus with approximately 70% accuracy at 12 weeks, increasing to over 95% by the 18–22 week anatomy scan. Although prenatal sex determination is prohibited by law in India to prevent sex-selective practices, the technology itself is capable of such detection [3]. Therefore, both statements are scientifically accurate regarding biological structures and medical imaging capabilities.
