Option C. Computer-enhanced x-rays are called CT scans.

Explanation:

A CT scan or computed tomography scan is a scan that uses computer-enhanced x-rays and combines them by taking them from different angles in order to produce cross-sectional images of specific areas of a scanned object, that allows seeing inside the object without the need to cut it. CT scans are commonly used by doctors to detect bone and joint problems as well to see if after an accident there is any internal damage or bleeding.
