The correct answer is a. Interrupt request (IRQ).An interrupt request (IRQ) is a signal sent to the processor by a device or a program, indicating that an event has occurred that requires immediate attention. When an interrupt occurs, the processor temporarily stops executing the current task and switches to a special interrupt service routine (ISR) to handle the event. After the ISR is completed, the processor resumes executing the original task.In the context of the question, the actual interrupting of an event by an interrupt signal is called an interrupt request (IRQ).
