A: Verify the AC adapter voltage: Power issue could cause shutdowns, not device failure. Incorrect. B: Repair the operating system: Not relevant since alternate devices are tested. Incorrect. C: Replace the user's USB-C hub: Faulty hubs cause multiple peripheral failures. Correct. D: Reinstall the drivers for affected devices: Driver issues wouldn't affect all peripherals. Incorrect. E: Make sure the printer is not drawing too much power: This is uncommon for peripherals via a hub. Incorrect. Step by Step Detailed Comprehensive Explanation with All CompTIA Reference: Analysis of the Problem: Multiple peripherals are non-functional, and the USB-C hub is a common point of failure.
