Sonography is a biological method that uses ultrasonic sound. It involves the use of high-frequency sound waves to create images of the inside of the body. These sound waves, beyond the range of human hearing, are transmitted into the body and reflected back to create detailed images of organs, tissues, and unborn fetuses, aiding in medical diagnostics.

Sonography (Option [A]) is a biological method that utilizes ultrasonic sound waves. Also known as ultrasound imaging, it involves the use of high-frequency sound waves (typically above 20,000 Hz) to create real-time images of internal body structures. During a sonographic examination, a transducer emits these sound waves into the body, where they bounce off tissues and organs, producing echoes. These echoes are then detected by the transducer and converted into an image displayed on a monitor.
Sonography is non-invasive, safe, and widely used in medical diagnostics to visualize organs such as the heart, liver, kidneys, and unborn fetuses. It helps in diagnosing conditions like pregnancy, tumors, cysts, and abnormalities in various organs. Unlike X-rays (Option [D]), which use ionizing radiation, sonography relies on harmless sound waves, making it suitable for repeated use without posing radiation risks. Therefore, among the options provided, sonography stands out as the biological method that harnesses ultrasonic sound waves for medical imaging purposes.
