Correct answer is (d) FAST interrupt request, Non vectored interrupt request and Non-vectored IQR

Best explanation: The vectored Interrupt controller accepts all the interrupts request INPUTS and CATEGORIZES them as Fast Interrupt Request, Vectored Interrupt Request, and Non Vectored IQR as defined by programmable settings.
