The correct answer is B. Bit-stream copy.
A bit-stream copy, also known as a bit-for-bit copy, is a method of copying a digital device or media that captures every bit of data, including deleted files, fragments, and unallocated space. This type of copy is essential in digital forensics as it preserves the original evidence and ensures that the investigation is conducted on a identical copy of the original data.
A bit-stream copy should always be performed first before carrying out an investigation to:
Preserve the original evidence
Ensure data integrity
Prevent data alteration or contamination
Allow for multiple investigations and analysis without modifying the original data
