Answer 1

The correct option is D Ultrasound

• Fetal ultrasound is a test done during the pregnancy to check the status, details, and defects of the fetus. In this process, the colored or black and white sonogram (picture) of the fetus, placenta, and amniotic fluid is displayed on a TV screen.
• 1st-trimester ultrasound is done to test the number of fetuses, estimate the age of the fetus (gestational age), chromosomal defect, birth defects related to the spinal cord and brain.
• The second-trimester ultrasound is done to estimate the age of the fetus, heart problems or neural tube defect, position of amniotic fluid and placenta, etc.
• The third-trimester ultrasound is done to check the movement and size of the fetus, position of amniotic fluid and placenta, etc.

Thus, the correct answer is option D.
