11. Given the codes as shown below: (10 marks) noPB is a NO pushbutton and ncPB is a NC pushbutton. Both red LED and yellowLED are LED lights. memBit1, memBit2, memBit3, and memBit4 all are bits in global memory zone. Initially the noPB and ncPB are in normal status, all the memory bits have a value, and both LED lights are off. Expect the LED lights' status (on or off) under the specified independent conditions by highlighting or circling one best choice in each situation.
