Show answer & explanation
Correct answer: B
The correct signal is a Time-out mechanism. Time-outs interrupt the processor when an operation exceeds a predefined duration, allowing for error recovery actions. Unlike polling (active checking) or handshaking/strobe (data transfer coordination), time-outs are specifically designed for interrupt-driven error handling in computer architecture.
