What are the available choices under the DeNIST Mode field?

The correct answer is focused on the option that best reflects the functionality provided under the DeNIST Mode field. When it states "DeNIST all files," it indicates that the mode can be set to apply the DeNIST process to every file within the selection, effectively cleaning the data from non-responsive, irrelevant, or duplicate items across the entire dataset.

This approach is particularly valuable in digital forensics and e-discovery contexts where ensuring that all files are analyzed helps maintain the integrity of the review process, allowing professionals to focus solely on relevant evidence without the distraction or obstruction of unneeded data.

The mention of processing "all files" suggests a comprehensive approach to DeNISTing, which is essential when aiming for thoroughness in data handling and analysis. Such processes can significantly improve the efficiency and effectiveness of subsequent reviews and analyses by providing a clearer, more manageable data set.

In contrast, the other options reflect limitations or specific instructions that wouldn't capture the breadth of the DeNIST function as effectively as "DeNIST all files." These options focus on restrictions or selective processing that may not be suitable for all contexts where a complete DeNIST application is desired.
