A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A user's iPhone is nearly out of storage. They want to reclaim the space a large app is using while keeping that app's documents and data. Which action in iPhone Storage does this?
Correct.
Checked against support.apple.com, August 2026Concept
iOS separates the installed program itself from the user content it holds. One storage action reclaims space and preserves that content, another discards both, and a technician has to know which is which before acting.
Why C
Offloading targets the installed program only, so the space it occupied is returned while its documents and data stay on the device for when the icon is tapped again.

Sample question 3 of 3
