Correct Answer: Option B
Explanation:
Sequential access requires the computer to read through data in the exact order it was stored, starting from the beginning, until it finds the target data. This makes it the slowest and least efficient method for retrieving specific files, compared to direct or random access which can jump straight to the data location.
