What are three image file formats that can be read by FTK Imager?

The correct choice identifies file formats that FTK Imager is specifically designed to handle within the context of digital forensics. E01 files, raw image files, and Safeback version 2.2 image files are standard formats used for creating forensic images of data.

E01, or Encase image format, is widely used in digital forensics for its ability to contain multiple disk images and metadata in a single file, making it essential for any forensic examination. Raw image files are direct copies of disk data, capturing every bit from the storage media, which is crucial for preserving the integrity of the original data during an examination. Lastly, Safeback is another imaging format often used in forensic contexts, allowing for the meticulous preservation and analysis of digital evidence.

In contrast, the other options list formats that are not primarily designed for forensic imaging or data preservation and may be associated with document or media file types that do not contain the same forensic integrity traits as those listed in the correct answer.
