Solution

The correct option is A Ultrasonics
Ultrasound is a technique which is developed in recent time to check the growth of the growing human foetus. It uses the ultrasonic waves to determine the structural growth of the baby.
But it is well known that these rays are harmful to the baby. The doctors usually stick to 3-4 ultrasounds during the normal pregnancy.
So, the correct option is 'Ultrasonics'
