Answers

(C) By checking the TRAP pin for high status at the end of the execution of each instruction The microprocessor recognizes interrupt request on request lines(RST7.5,RST 5.5,RST 6.5,TRAP,INTR) at the end of current instruction execution. TRAP is non maskable interrupt .TRAP is active high ,level,edge triggered non maskable highest priority interrupt.when TRAP line is active microprocessor insert intervals restarts automatically at vector location of TRAP. So correct option is (C)
