Explanation

A hard reset restores the device to factory software state, which would resolve software-based issues such as missing or corrupted drivers (Option A) and most virus infections (Option B). If the touchscreen remains unresponsive after a hard reset, the problem is hardware-related. The digitizer-the hardware layer that translates touch into input signals-is the most likely culprit if it is physically damaged. Low battery (Option C) would typically prevent the phone from powering on entirely, and would not cause a selectively unresponsive touchscreen after a reset.
