Explanation

IBM BIOS POST error codes use specific number ranges to indicate hardware failures. The 3xx range specifically indicates keyboard-related errors during the Power-On Self-Test. Other ranges include 1xx for system board, 2xx for RAM, and 4xx for video/monitor issues, making 3xx the correct answer for keyboard problems.
