Final answer:
The statement is true as FTK can indeed be used to preview data and create images, aiding in digital investigations by maintaining the integrity of original evidence.
Step-by-step explanation:
The statement that the Forensic Toolkit (FTK) can be used to both preview and create an image is true. FTK is a widely recognized digital forensics software that allows investigators to preview data to quickly assess whether further analysis is needed or if it's relevant to the case. Additionally, FTK provides the capability to create disk images, which are exact duplicates of the data on a hard drive or other storage devices, ensuring that the integrity of the original evidence is maintained during the investigative process.
