The correct option is B Echocardiography

Echocardiography: The technique of obtaining images (pictures) of the heart by using ultrasonic waves is called echocardiography. In this technique, ultrasonic waves are sent to the various parts of the heart. The ultrasonic waves travel through the tissues of the heart and get reflected. The reflected ultrasonic waves are then converted into electrical signals and fed to the computer which form the image of the heart. This technique is used to study congenital heart diseases.
