Explanation / Answer

Answer:-1) 3rd option is correct. When O1 is ON, then pressing I2 momentarily will make O1 false. If I1 is still true then O1 will be fasle for time till I2 is pressed otherwise O1 will false until I1 is pressed again.

Answer:-2) All statements are correct. In full light I3 will be closed but until I1 is pressed motor will be off.
