In an HSM archive application, which of the following is the BEST candidate for migration?

A 1 MB file, even if 360 days old, is small; migrating it frees up minimal primary storage space compared to larger files, making it a less impactful candidate for HSM.

A file about to expire relates to its retention policy for deletion, not necessarily its access frequency or suitability for migration to an archive tier based on HSM's typical criteria.

A 250 MB file that has not been referenced for 90 days is an ideal candidate for HSM migration. Its relatively large size means migrating it frees up substantial space on primary storage, and its long period of inactivity indicates it is cold data that can be safely moved to a cheaper, slower archive tier without impacting active users.

A 1 MB file that is 120 days old is a small file, similar to choice A, which would provide less benefit in terms of freeing up primary storage compared to a much larger inactive file.
