Which of the following best describes the function of deduplication?

Deduplication serves a specific purpose in managing data, particularly in document review processes. It involves identifying and removing duplicate copies of documents within a dataset. By eliminating these redundancies, the review process becomes more efficient, as reviewers can focus on unique documents rather than sifting through multiple instances of the same item. This not only saves time but also reduces storage requirements, allowing for a more organized and effective workflow.

Options that suggest increasing file size, enhancing security, or categorizing documents based on content do not align with the primary function of deduplication. Rather than adding data or improving security, deduplication specifically aims to streamline operations by ensuring that only distinct documents are included for review. This simplifies the overall management of documents and leads to improved performance during the review stages.
