Mariam's mother had an ultrasound to see the baby growing inside of her. Which statement explains how ultrasound works? A. A special cream is heated and placed on her mother's stomach area, which produces an image on a computer. B. A fluorescent light is used to transmit light waves into her mother's body, which produce an image on a computer. C. Sound waves are sent into her mother's body, which reflect off of the baby and produce an image on a computer. D.
