Step by Step Detailed Comprehensive Explanation with All CompTIA References: * Analysis of the Problem: * Multiple peripherals are non-functional, and the USB-C hub is a common point of failure. * Option Evaluation: * 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. Reference: USB-related troubleshooting in Domain 5.1 and peripheral failures.
