Answer No:5 is fully correct.
1. Prtects the equipment and passes the short circuit through the ground to the generating or sub-station.
2. If you do not ground the neutral, then you have a floating neutral which will cause imbalance in voltage of the other phases and the earth to neutral voltage will also come into play. Incase the other two phases have any single phase equipment hen they will get a lower voltage due to the floating neutral, which could be as high as 60-90 volts betweem earth and neutral, causing tube lights to dim etc.
