Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Back up data, then navigate to Settings > System > Reset options, then confirm the reset, then wait for the device to reboot.

  Why this is correct

  Backing up first is non-negotiable because a factory reset formats the /data partition, permanently erasing all app data, SMS, call logs, and device settings. Once backup is secured, the correct path is Settings > System > Reset options, where the 'Factory data reset' (or 'Erase all data') button resides. Confirming that button triggers the wipe-and-reboot cycle, after which the device boots to a fresh setup wizard. This order ensures that no user data is lost and that each step logically depends on the previous one.

• ✗

  Navigate to Settings > System > Reset options, then back up data, then confirm the reset, then wait for the device to reboot.

  Why it's wrong here

  Though this sequence still performs the backup before confirmation, it needlessly postpones backup until after the user has opened the destructive Settings menu. Inside that menu, a single accidental tap on 'Reset device' or 'Factory data reset' could immediately wipe the phone before the backup is executed. Even without a mis-tap, it's poor practice to enter a high-risk environment before securing your data; the backup should be an isolated first action, so there is zero chance of losing data due to navigation-related missteps.

• ✗

  Back up data, then confirm the reset, then navigate to Settings > System > Reset options, then wait for the device to reboot.

  Why it's wrong here

  This ordering invalidly assumes you can confirm a reset you haven't yet initiated through the reset menu. The confirmation prompt (typically a dialog asking 'Are you sure?' with an 'Erase everything' button) only exists after you tap 'Factory data reset' inside Settings > System > Reset options. Attempting to confirm before navigating is a logical impossibility; there is no active reset process to confirm. Furthermore, the 'wait for reboot' step must follow confirmation, not occur before the system has any recorded prompt, so this entire ordering is non-functional.

• ✗

  Navigate to Settings > System > Reset options, then confirm the reset, then back up data, then wait for the device to reboot.

  Why it's wrong here

  This is the most dangerous sequence because it places backup after confirmation, making it too late: confirming the reset triggers the device to begin formatting the userdata partition immediately. By the time you attempt to back up, the partition is already erased (or locked from reads) and your data is unrecoverable. Even if the phone hasn't physically formatted yet, the confirmation is a signal to the system that the wipe is imminent, so no valid backup can be taken afterwards. This ordering causes permanent data loss and is the exact kind of mistake a pre-step backup is meant to prevent.
