a. communication
b.computer applications
c.energy,power and transportation
d.bio-related

Answer:
d
Answer : D

A sonogram uses nouns waves … much similar to the sonar on a ship. The sound breakers come from a special wand (transducer) and travel into your body. They bounce off of the structures within your body and travel back to the transducer. The mechanism translates this information into a "real-time" image on a TV peak. A radiologist can visualize the structures in amazingly fine detail and will inform your doctor of your results.
